In the kit:

  • CAN-cable 1,2-meters length for connection to the On-board Computer.
  • Phase wires.
  • Battery wires
  • Hall sensors wire.

Phase, battery, and Hall sensors wires are supplied with connectors, depending on the type and specification of the controller in the order.

Optionally you can order:

  • САN-cables 0,3 and 2 meters length.
  • Controller-side inputs for connection throttle, brakes levers directly to the Controller.
  • PWM/PAS wire for connection PAS, fans for cooling or brake lights.

Connection diagram

First, connect the three phases of the electric motor. It does not matter in which order and by which color you connect the phases, the controller will automatically detect them during auto-setup. Next, connect the hall connector as shown in the diagram below. You also need to connect the throttle lever and battery power. We also recommend connecting the brake levers, as their actuation turns off the motor. A simple rule — in any incomprehensible situation, press the brake.

When the power is turned on for the first time, the controller will start automatically. To enable/disable the controller, you must connect an external switch according to the diagram or configure the button located on the back of the On-board computer in the menu Devices > Controller > Extra parameters > Disable button.

You can find the wiring diagrams of the other devices on this link. By default, all peripherals (throttle, brake, switches, etc.) are connected into ports located on the backside of On-board computer. To access the ports, you need to unscrew five screws and remove the plastic cover. For connection, use PHD 2.0 connectors and crimp pins, which are included in the kit. If you do not have a crimping tool such as Crimper SN-2549, you must order “Crimped wires for display”. The On-board computer is connected to the controller with one CAN-wire 1.2 meters long, which is included in the controller kit. Be careful, the CAN-wire from the Controller is connected to the SYSTEM connector on the backside of the On-board computer.

If you want to connect peripherals directly to the Controller, you need to order “Control-side inputs”, in the diagram below this switching option is designated as “Alternative connection”. You can also use a mixed connection, for example, connect the throttle lever to the On-board computer, and the brake lever to the Controller.


Connecting multiple controllers

If you want to connect two or more Controllers, you can use a CAN splitter with four ports (purchased separately) or a lighting controller uLight, which also has three own CAN ports. The On-board computer supports the connection of up to eight Controllers.

For example, for a two-motor connection scheme, which is used on all-wheel-drive electric scooters, in addition to the second controller, you will need a CAN-splitter and one more CAN wire (there are 2, 1.2, and 0.3 meters long). Each Controller has a standard CAN-wire 1.2 m long. These wires from both controllers must be connected to a CAN-splitter, and from it one CAN-wire connects directly to the On-board computer. In the On-board computer, you can configure both controllers are separate.


Pay attention to the connection diagram. Do not disconnect power grounds when system wires are connected! First connect all power wires and only then CAN wires. When disconnecting the controllers, first disconnect all CAN wires and only then disconnect the power cables; it is also recommended to discharge the controller capacitors with a resistor or an ordinary light bulb.


How to start?

After you have connected the Controller and Controls according to the diagram, you need to configure the battery parameters. For this, go to the Settings > Devices section, select the Controller in the list of devices, then go to the Controller > Battery section and specify the supply voltage range. For a detailed description, see the section Battery.

After configuring the battery, you need to run Auto-setup in the Controller > Auto-setup menu section. Ensure that the phase and battery wires are well contacted and insulated before running auto-setup. Check that the Hall sensor wire connectors are fully inserted into the mating parts. For details, see the section Auto-setup. After auto-setup, you need to adjust the speedometer to display the speed correctly, see the section Speedometer setup.

Menu navigation

Use the On-board computer buttons to navigate through the menus. Left button — return to the previous menu or cancel editing. Right button — go to the menu section and confirm the parameter selection. The two middle buttons — to move up/down through the menu and select the value of the menu item.

Settings saving

In the menu item Controller > Save settings you can save all the settings made. Press the right button of the Onboard-computer and select On to save. If you do not save the settings, they will be reset after restart.

Auto-setup

The auto-setup function in the Controller > Auto-setup menu section allows you to automatically set up the electric motor, throttle, and brake levers.

The auto-setup menu starts the subprogram and shows only the process. All settings are saved under Controller > Motor setup. After restarting the Controller, all switches will be in the Off position.

Once you have specified the battery supply voltage in the Controller > Battery section, you can proceed to calibrate the motor and levers in the Auto-setup section.

Before auto-setup the angles, we recommend specifying the correct number of motor pole pairs in menu item Controller > Auto-setup > Pole pairs. See Motor information for this number for the most popular motors. If your motor is not on the list, check with the manufacturer or search the Internet for information.


Be careful! Before running autotuning, check that the drive wheels of your e-bike are not touching the surface and that the pedals (if equipped) do not touch anything when spinning. When adjusting the Hall sensors, the motor rotates in both directions, be careful and do not stand near the bicycle pedals. The motor will rotate five times, once when the motor is detected and four times when correcting the angle.


If you have a throttle lever and an analog brake connected, then you need to enable Full Setup, and follow the instructions on the On-Board computer screen. The corresponding menu items will indicate when to press and release the throttle or brake lever.

If only one throttle lever is connected, you must independently turn on the items step-by-step: Throttle, Motor, Angle correction. When you enable each of the menu items, the hints will be displayed.

If the motor is heavy and autodetect does not happen, you can gently push it with your hand or increase the tuning current in the Controller > Auto-setup > Setup current section, for example, twice. The setup current can be selected in the range from 2A to 50A, in increments of 1A.

If the motor is rotating in the wrong direction, go to Controller > Auto-setup > Spin direction and change the direction of rotation. You can choose from two options Forward or Invert. A similar setting is available in the Controller > Motor setup> Spin direction menu. It doesn't matter in which menu you make the setting, after saving, the direction of rotation will be reversed in both sections.

If an error occurs during autotuning, see the section Diagnostics of controller malfunctions. In the menu item Controller > Auto-setup > Control source you can select the sources of control for the Controller. See Control Source section below for details.

Firmware update

In the menu section Controller > Settings and Update, you can update the Controller's firmware, reset settings, import or export a configuration. You can upload all controller settings to a microSD card. The created file with the name NCconf.cfg - NCconf9.cfg you can open with the “Notepad” program, see all your settings, make any changes, save. Likewise, you can import a previously saved configuration into the Controller. Trip computer settings cannot be exported or imported.

Import config. — loads the settings from the file NCconf.cfg - NCconf9.cfg up to a maximum of 9 different configurations, choosing a file number from 1 to 9. After a successful import, error messages may appear in the message, this means that not all the settings have been imported. In this case, it is advisable to check the downloaded settings with the original file by opening it in Notepad.

Export config. - saves the settings to the NCconf.cfg - NCconf9.cfg file up to a maximum of 9 different configurations, choosing a file number from 1 to 9.

Reboot — restarts the device. If the settings have not been saved, they will be reset.

Reset Wh usage — resets the accumulated number of Watt-Hours in the controller. This indicator is displayed in the statistics of the On-board computer, see section Statistics.

Reset stats — resets mileage in kilometers.

Load defaults — after a reset, the default settings are loaded but not saved. If you restart the Controller without saving after a reset, the previous settings will be loaded.

Erase data storage — This function may be needed for the correct firmware update, rollback to default settings, in a situation where user actions lead to incorrect operation of the Controller. If the controller has stopped saving the settings, do a reset, wait 3 seconds, and try to save again.

Update firmware — starting the firmware update process. You can download the current firmware version and read the rules of update in the Firmware section. To update, download the firmware file to the root directory of the microSD card with the Fat/Fat32 file system. Insert the card with the contacts facing up into the slot on the On-Board Computer and select On . When the update process is complete, a message appears on the screen Update finished. Press the left button and check the update version under Controller > Device Information.

Control modes

In the menu section Controller > Control modes you can configure and save three presets of the parameters of the electric motor and switch between them using a 3-position switch or buttons on the On-board computer. The currently active mode number is displayed at the top of the main screen. After setting, it is necessary to activate the modes in the menu item Controller > Additional modes > Enable additional modes by setting the value On. In the same menu Controller > Additional modes you can make detailed settings for each mode (see the section Additional modes).

If there is no speed switch, then mode 1 is the default. If the switch is connected to the On-board computer, it is necessary to configure the On-board computer buttons in the On-board computer > Button settings menu. See section Buttons setup.

Modes setup

The # Current mode line displays the currently selected control mode. List of possible options:
N — neutral.
S1 — speed 1.
S2 — speed 2.
S3 — speed 3.
RV — reverse.

Four parameters are used to configure each mode:
Phase — the maximum value of the phase current, in Amperes (A). Select of values from 0A to 500A, in increments of 2A. When setting, consider the maximum phase current of your controller type. In most cases, we recommend specifying the value of the phase current 1.5-2 times higher than the battery current.

Battery — the maximum value of the battery current, in Amperes (A). Select of values from 2A to 400A, in increments of 2A. When setting up, consider the capabilities of the connected battery and the maximum battery current of your controller type.

Power — maximum power (discharge) of the battery, in kilowatts (kW). Select of values from 0.00kW to 30.0kW, in increments of 0.1kW. Set to 0.0kW to disable the power limiting limit.

Speed — maximum speed in percentage (%). Select of values from 4% to 150%, in increments of 2%. The value of this parameter determines the percentage of speed depending on the reference speed (see section Speedometer setup). A speed value over 100% activates the field weakening mode, which allows the motor to accelerate above the supply voltage. (see section Field weakening setup).

Electric brake setup

Braking phase — the value of the phase current of braking by the motor, in Amperes (A). Select of values from 0A to 500A, in increments of 2A. For braking to zero, it is recommended to enable Active braking in the section Controller > Control. When using the switch brake, lower brake current change speed makes recuperation more smooth.

Braking phase at speed control

Braking ph. at speed — phase braking current during speed control, in Amperes (A). Select of values from 0A to 500A, in increments of 2A. This function allows you to slow down when you reset the throttle stick. Works only with Direct Drive motors, without a clutch.

Also to use this mode should be selected: Speed or Speed and Torque mode in the Controller > Control > Throttle Mode menu item. In the menu item Controller > Control > Speed lim. at 0% throttle enable the speed limit at 0% throttle (optional), enable if you need braking with completely released throttle.

Reverse setup

Speed reverse — reverse speed, in percentage (%). Select of values from 2% to 150% , in increments of 2% . The value of this parameter determines the percentage of speed depending on the reference speed (see section Speedometer setup). A speed value over 100% activates the field weakening mode, which allows the motor to accelerate above the supply voltage (see section Field weakening setup).

Phase reverse — the value of the reverse phase current, in Amperes (A). Select of values from 10A to 500A, in increments of 2A.

Field weakening setup

Field weakening — the magnitude of the field weakening current, in Amperes (A). Select of values from 0A to 500A, in increments of 2A. This setting allows you to increase the maximum motor speed and depends on the supply voltage, in any case, the speed will be no more than the maximum supply voltage (Vmax) of the controller (95V limit).


The current of weakening creates a field that acts against the field of the permanent magnets. The superposition of these fields creates an equivalent field that is below nominal. The attenuation efficiency depends on the parameters of the motor. The best results can be obtained with IPM motors.


To set up the weakening, you need:

  • for one of the control modes in the section Controller > Control modes specify a speed value greater than 100%, for example, Speed 3 is 120%.
  • set the weakening current value in the section Controller > Control modes, you can start from 30A.

Field weakening is activated when the maximum speed is reached, the Controller adds weakening current, limiting the phase current and weakening current specified in the control mode. That is if the effective phase current is 70A, and the weakening current is set to 30A, then a minimum of 100A must be specified in the phase current settings. If the phase current increases to 80A, then only 20A will remain for weakening because 80A + 20A = 100A.

Also, the Controller will limit the speed of rotation of the motor so that its effective EMF does not exceed the maximum supply voltage of the controller (not the battery). If the motor starts twitching on the suspended wheel, then it is necessary to reduce the weakening current.

Current change speed

# Current change speed.

  • acceleration, select of values from 50A/s to 50000A/s, in increments of 100A/s.
  • braking, select of values from 50A/s to 50000A/s, in increments of 100A/s.
  • shutdown, select of values from 50A/s to 50000A/s, in increments of 100A/s.

Three parameters determine the rate of change of the current (smoothness). The higher the value, the faster the current build-up in the motor will occur. For conventional brake levers, it will be useful to reduce the parameter braking for a smoother activation of the regeneration. If the throttle response seems too slow, you need to increase the parameter acceleration. The parameter shutdown determines how quickly the current drops after throttle and brakes are released.

Advanced control modes

In the menu section Controller > Advanced modes enables the control modes and activates the advanced settings for each of these modes.

To activate the control modes, select Controller > Advanced modes > Enable add. modes and to set On.

In the menu Controller > Advanced modes > Neutral by default you can activate the neutral mode (N) when the controller starts up, which will be active until one of the speed modes is activated. In a neutral mode, only the electric brake operates, throttle and PAS are disabled. This mode is recommended for use with speed buttons (not a switch). The function does not work with a 3-position switch (functions of the S1of3 and S3of3 ports in the Controller > I/O configuration menu). ​

Each mode has its own section in the Controller > Advanced modes > Mode S1, Mode S2, Mode S3 with the following settings:

Throttle mode — selection of the operating mode of the throttle lever, read more in the section Throttle control mode setup.

Acceleration lim. and Deceleration lim. — are specified in ERPM/s, select of values from 0 ERPM/s to 500000 ERPM/s, in increments of 200 ERPM/s . These settings allow you to limit the speed of acceleration or deceleration of the motor, it is convenient to use on slippery surfaces. For setting go to the Controller > Status flags section, in this menu there are two parameters that register the maximum acceleration and deceleration — Max acceleration and Max deceleration. Reset the values of these parameters in the same section of the menu, then you need to ride your e-bike in order to register the current dynamics of acceleration and deceleration. You can use these values as a reference and decrease them if you need to limit change speed. If the type of surface changes, for example, it becomes too slippery, then these values can be reduced until it becomes comfortable to catch the moment when the wheel loses traction.

Revers — reverse gear activation when the control mode is selected. Select of values On or Off.

Cruise — activation of the cruise function. Select of values On or Off. Convenient to use with cruise mode Allow Throttle hold in the menu section Controller > Control > Cruise > Cruise to enable cruise in certain modes. See section Cruise control setup.

Disable motor — completely disables motor control. Select of values On or Off.

Disable throttle — disable throttle control. Select of values On or Off.

Active braking — allow the brake to use the battery for stopping. Select of values On or Off.

Reverse on brake — after stopping, pressing the brake lever again activates reverse speed. Select of values On or Off.

Speed lim. at 0% throttle — allows limiting the speed when the throttle lever is released. Select of values On or Off. Selecting Off disables motor control when the throttle is released.

Disable PAS — disables the Pedal Assist. Select of values On or Off.

PAS Scale — extra PAS multiplier for tuning, decreases PAS signal for smoother control on high power modes. Select of values from 1% to 100%, in increments of 1%.

Control

In the Controller > Control menu section you can setup setting the engine controls, throttle levers, torque and PAS sensors, cruise control.

PAS and Torque sensor setup

In the menu section Controller > Control > Pedal Assist System you can set up the Pedal Assist System (PAS), which connects the electric motor when pedaling.

ЧTo be able to connect the PAS system, it is necessary to order the PWM IO/PAS cable as an option. The PAS system connects to the Controller via the PWM IO/PAS wire to the P1/P2 ports of the USB/PWM connector. When using a SEMPU pressure sensor, an additional signal output from the TH port of the connector Control is required.

You can look at the connecting methods of various PAS systems at Connection diagram.

The PAS, unlike the Torque sensor, controls the throttle by frequency and not by the force of rotation. The PAS setup menu consists of the following items:

PAS — selection of pedaling assistant type PAS sensor or Torque sensor. If there is no PAS system, select Disabled.

PAS connection — 1-wire or 2-wire connection option, two wires are used for the angle sensor (encoder).
Invert PAS — change of direction in case of 2-wire connection. Select of values On or Off.
PAS poles — number of impulses per pedal revolution. Select of values from 1 to 200, in increments of 1.
PAS min. freq. — the minimum pedal speed (cadence) at which the motor starts, RPM. Select of values from 1 RPM to 500 RPM, in increments of 1 RPM.
PAS max freq. — the maximum pedal speed (cadence) at which the motor starts, RPM. Select of values from 10 RPM to 1000 RPM, in increments of 5 RPM.

# PAS freq. — the value of the signal coming from the PAS in real-time.
PAS timeout — the time after which the motor turns off after stopping pedaling, in seconds (s). Select of values from 0.02s to 5.00s, in increments of 0.02s.
PAS filter — smoothing the control signal for smoother operation, in hertz (Hz). Select of values from 1 Hz to 100 Hz, in increments of 1 Hz.
PAS min out — minimum control level when PAS is running, in percent (%). Select value from 0% to 100%, in increments of 1%.
PAS max out — maximum control level, in percent (%). Select of values from 0% to 100%, in increments of 1%. By analogy with the “pressed” throttle, PAS sends a signal within the specified limits.

Further in the menu are the settings related to the pressure sensor (Torque sensor).

Pressure scale — in Newton-meters/volts (Nm/V). You can calibrate by placing a load on the pedal and calculate the torque on the shaft through the lever. Select value from 0.0 Nm/V to 100.0 Nm/V, in increments of 0.5 Nm/V.
Zero pressure — zero pressure, in millivolts (mV). Select of values from 0mV to 10000mV, in increments of 10mV.
Protection pressure — switching off the pressure sensor when the threshold of the specified value is exceeded, in millivolts (mV). Select of values from 0mV to 10000mV, in increments of 100mV.
Torque averaging — period for which is torque value updated. Measured in half turns (turn/2). If the torque sensor measures only one pedal, then the period must be a multiple of two. Select of values from 1 turn/2 to 20 turn/2, in increments of 1 turn/2.

# Torque — shows the current torque at the sensor, in Newton-meters (Nm).

# Human watt — shows the average power you develop when pedaling, in watts (W).
Human watt min — the minimum power you develop to activate the motor, in watts (W). Select of values from 0 W to 500 W, in increments of 10 W.
Human watt max — the maximum power for 100% activation, in watts (W). Select of values from 0 W to 1000 W, in increments of 10 W.

Torque min — the torque at which the throttle signal starts to increase, Newton-meters (Nm). Select of values from 0 Nm to 100 Nm, in increments of 2 Nm. All values less than this level is 0% of throttle.
Torque max — the torque, which limits the level of 100% throttle, Newton-meters (Nm). Select of values from 0 Nm to 300 Nm, in increments of 2 Nm.
Instant Torque — allows torque sensor activation without rotation. Select of values On or Off. The pressure sensor also includes frequency configuration and output level configuration as well as the usual PAS.

Remote control

The Controller > Control > RC Control menu section allows you to configure the remote control of the Controller using an external RC receiver.

Input for radio control via PWM (PWM), connects to the P1 port of the USB/PWM connector on the Controller board. To activate the function, select the PWM value in the P1 Input Mode menu item.

The # Input Freq. and # Width menu items show the current signal value in hertz (Hz) and milliseconds (ms), respectively.

In the menu item Function selects the control function — Off, Throttle, Brake or Throttle and brk.


Adjust the throttle and/or brake range as indicated by the signal.

# Throttle range
Throttle min — minimum throttle value, in milliseconds (ms). Select of values from 0.00 ms to 10.00 ms, in increments of 0.01 ms.
Throttle max — maximum throttle value, in milliseconds (ms). Select of values from 0.00 ms to 10.00 ms, in increments of 0.01 ms.

# Brake range
Brake min — minimum brake value, in milliseconds (ms). Select of values from 0.00 ms to 10.00 ms, in increments of 0.01 ms.
Brake max — maximum brake value, in milliseconds (ms). Select of values from 0.00 ms to 10.00 ms, in increments of 0.01 ms.

Cruise control setup

In the menu section Controller > Control > Cruise you can set up the cruise control function. After connecting buttons or switches for cruise control to the ports of the Controller or Onboard Computer, you need to configure the functions that relate to cruise control:

CRe — cruise activation.
CR+ — increase cruise speed (when active).
CR- — decrease cruise speed (when active).
CRr — restoring cruise (turning on the last saved speed).

For more information about configuring these functions, read the I/O port configuration section below. If the cruise control button is connected to the On-board computer, then you need to configure it in the Buttons setup section.

In the Cruise menu item, you can select several control modes:
Disabled — cruise control disabled.
Button — activation of cruise control at the push of a button. The response time of the button is determined by the parameter Cruise EN time.
Switch — activation of cruise control by turning on the switch, time is not used.
Throttle hold — activation of cruise control by holding the throttle for a certain time in one position. The response time is determined by the parameter Cruise EN time. The accuracy is set by the parameter Cruise by throttle in percent (%). Select of values from 1% to 30%, in increment of 1%. Accuracy is essential, as the throttle lever moves slightly during the ride due to shaking. The default is 2%.
Allow Throttle hold — similar to the previous mode, with the difference that to activate the cruise control, you must additionally press the cruise button.

Next are the menu items for setting the cruise:

Cruise restore — this function activates the last saved cruise speed. To enable, select the CRr function when configuring I/O ports. The function can be deactivated by selecting the parameter Disabled.

Cruise EN time — setting the cruise activation delay in seconds after enabled button (s). Select of values from 0.25s to 30.00s, in increments 0.25s.

Cruise level — selects what speed cruise will use:

  • Throttle — speed depends on the position of the throttle lever, turns on instantly.
  • Speed — cruise enables when Safe acceleration reached after that uses current speed as a reference.
  • Mixed — if controller cant use speed reference, uses throttle value.

Cruise smoothness — this setting limits acceleration during cruising so that there are no jerks, measured in electrical revolutions per minute per second (ERPM/s). To get the value in rpm, the ERPM/s value must be divided by the number of pole pairs of the electric motor. Select of values from 0 ERPM/s to 50000 ERPM/s, in increments of 50 ERPM/s.

# Used for cruise activation:
Safe acceleration — limits the acceleration at which the cruise is activate, for example, to prevent it from engaging when accelerating, in electrical revolutions per minute per second (ERPM/s). Select value from 100 ERPM/s to 10000 ERPM/s, in increments of 100 ERPM/s.
Min. speed — speed below which you can not activate cruise or recovery, in kilometers per hour (km/h). Select of values from 3 km/h to 127 km/h, in increments of 1 km/h.

Additionally, to control the cruise, you can use the CR+ and CR- functions for the buttons, which adjust the cruise speed when it is active.

What actions disable cruise control:

  • pressing the brake, analog or digital.
  • repeated throttle press.
  • if a switch is used — when it's disabled.
  • reverse enable.

Throttle and brake curves setup

In the menu section Controller > Control > Throttle/brake curves you can set up the behavior of the throttle and brake levers. In Throttle preset and Brake preset menu items you can select one of the typical settings, select one of the throttle or brake presets, and press enter, the preset will be loaded.

You can select the following types of throttle and brake presets:
Linear — smooth increase, direct dependence.
Exponential — slow increase.
Normal — average between linear and exponential.
Polynomial — average between normal and exponential.

Manual setting of throttle and brake position points is also available, to do this select None in Throttle preset or Brake preset and enter the value manually. There are eight position points available for throttle and brake::
Start — starting point, in percentages (%). Select of values from 0% to 100%, in increments of 1%.
1-6 — midpoints, in percentages (%). Select of values from 0% to 100%, in increments of 1%.
End — end point, in percentages (%). Select of values from 0% to 100%, in increments of 1%.

You can also manually edit the value of each point in the loaded preset.


Control source

The controller supports the connection of controls (throttle, brake, switches, and buttons) to the Controller, On-board computer, ulight board, or mixed connection when one part of the periphery is connected to the Controller, and the second part to the On-board computer, or to ulight and On-board computer. This is necessary in the case of Tork/PAS sensor configurations in the Controller + throttle lever in the On-board computer. In the menu item Controller > Control > Control Source you can set up the control source of the Controller`s.

Select of control options:
Auto — all sources will control the Сontroller. Built-in and external, connected via CAN bus (for example, On-board computer or ulight).
Embedd — only what is connected directly to the Сontroller.
Remote — control only via CAN bus (via On-board computer or Microlight).
Disabled — disables any control of the Controller.


Throttle control mode setup

The menu item Controller > Control > Throttle modes you can set up throttle lever mode.

Three throttle modes options are available:
Speed — a similar mode is used in Infineon controllers and non-programmable low-cost controllers and is characterized by the use of maximum current to reach a given speed. In this mode, the maximum thrust is used until the desired speed is reached, the thrust is not regulated by the throttle grip.
Torque — in this mode, the throttle controls phase current, the thrust is limited by the angle of rotation of the throttle.
Speed+torque — combined mode (as Kelly), similar to the operation of the gas pedal in a car with an internal combustion engine.

In the case of selecting the Speed+torque mode, pressing throttle to 50%, when achieved 50% speed, the current consumption will be reduced to hold speed. The acceleration current will also be proportionally lower.

Throttle and brake voltage range setup

The menu items in the Controller > Control section allow you to set the voltage ranges of the throttle and brake grips.

Currently, voltage settings for all throttles and brakes are common.
# Throttle — shows the voltage of throttle grip connected to the controller, in volts (V).
Throttle min and Throttle max — range of the throttle grip, in millivolts (mV). Select of values from 0 mV to 15 000 mV, in increments of 10 mV. If the maximum value is exceeded by 5%, protection against a broken throttle grip will be activated. If the range is incorrectly set, then when you fully press the throttle grip, the electric motor will turn off, in this case, you need to increase the range value.

# Brake — shows the voltage of the brake connected to the controller, in volts (V).
Brake min and Brake max — range of the analog brake lever, in millivolts (mV). Select of values from 0 mV to 15 000 mV, in increments of 10 mV.

Invert brake — inverts the voltage value from the built-in brake lever. Select On to enable. It is useful to enable when the voltage brake lever with reverse voltage is connected to the On-board computer and you want to use the value Auto in the menu item Controller > Control > Control source. The digital brake grip (i.e. button) connects to the On-board computer, see section Buttons setup.

Setup 100% speed value

The menu items in the Controller > Control section allow you to adjust the 100% speed level. The maximum speed in the field weakening mode is 150%.

Speed ref. filter — filter mode selection. Select of values OFF, Linear, Quadratic, Cubic. For the control modes Speed and Speed+torque, a speed reference filter is applied, for a smoother response to the throttle change. The filter algorithm calculates the difference between the previous speed request and the current one, multiplies the error by a power of 1,2,3 (linear, quadratic, and cubic, respectively), and multiplies by a factor. The resulting value is used as the cutoff frequency of the low-pass filter. The larger the change, the sharper the response to it.

Filter factor — sets the filtration factor. Select of values from 0 to 30000, in increments of 100.

Speed mode allows you to select the level of 100% speed and what it depends on:

  • OFF — completely disables speed control PID.
  • Middle U bat — the average value between the minimum and maximum voltage of the battery settings used as speed reference, depending on motor kV.
  • U supply — supply voltage used as speed reference, depending on motor kV.
  • Ref. speed — speed in km/h, is set by parameter Reference speed. The speed value is taken from the motor or from an external speed sensor connected to the controller.
  • Ref. ERPM — speed in motor electric RPM, is set by parameter Reference speed.

Motor setup

The Controller > Motor Setup menu contains all settings related to electric motor operation parameters.

Motor temperature sensor

In the menu section Controller > Motor setup > Motor t°-sensor you can select a temperature range in which a smooth power limit will occur (Delta °t parameter) and specify the maximum temperature (°t max).

°t max — maximum electric motor temperature, in degrees Celsius (°C). Select of values from 50°C to 200°C, in increments of 1°C.
Delta °t — the temperature value that is deducted from the maximum temperature (°t max), the resulting temperature value will be the beginning of the power limit, in degrees Celsius (°C). Select of values from 1°C to 100°C, in increments of 1 °C.

It is recommended to install a temperature sensor so close as possible on the stator windings, while not in contact with the stator iron. If you don't know what kind of sensor is in the motor, you can check all types of sensors and select the one that displays data the most closely to room temperature. The current measured temperature is displayed at ## Value °t ##.

In the menu item Sensor type you can select the following types of temperature sensors that support the controller — KTY81(82), KTY83, KTY84, NTC10K (B:3950), NTC10K (B:3380), PT1000. To disconnect the temperature control, select the value OFF.

Clutch

In the menu section Controller > Motor Setup > Clutch you can configure a smooth engine launch for soft engagement clutch or freewheel. Useful for gear motors or mid-drives. At the moment, the setting works well only in the control mode Torque, because the clutch there is always engaged. An alternative option is to configure the acceleration limit in the modes S1, S2, S3 in the menu section Controller > Advanced modes.

The parameter Mode determines the way of operation::
Accelerate — smoothly accelerates the motor until the load appears.
Accelerate and hold — in addition to the previous one, it applies weak torque to the motor after the throttle is released, this mode allows you to switch speeds at mid-drive systems without using the pedals.

# Phase amps
Start time — maximum time for soft start, in seconds (s). Select values from 1s to 20s, in increments of 1s.
Start current — phase motor current at which the load will be detected and the soft start is disabled, in amperes (А). Select values from 0.2А to 50.0А, in increments of 0.2А. This value must be higher than the phase current for specified acceleration of the motor without load.
Detection time — the time during which the load must be present, after which the soft start will be switched off, in milliseconds (ms). Select values from 10 ms to 1000 ms, in increments of 10 ms.
Acceleration — value in volts/seconds (V/s). Select values from 2V/s to 1000V/s, in increments of 2 V/s. The higher the value, the more you need to specify Start current, since the motor will consume more current during acceleration.
Hold (20%) and Hold (80%) — two parameters regulating the phase current supplied to the motor in the mode Accelerate and hold, in amperes (А). 20% — current at low speeds, 80% — current at about maximum speed. It is possible to determine the approximate values ​​by the no-load current of the motor. Select values from 0.2А to 50.0А, in increments of 0.2А.
Hold enable time — time through which after the throttle has been pressed, torque hold will become available, in seconds (s). Select values from 1s to 120s, in increments of 4s.

Hold time — the time during which torque will be applied after releasing the throttle, in seconds (s). Select values from 1s to 120 s, in increments of 1s.


Optimal settings for MAC motor: Accelerate, 15a, 50V/s, 200ms.

Manual setup the Hall sensors angles

In general, it is not recommended to change these settings manually!
In the menu section Controller > Motor settings > Manual angle setup you can set up the Hall sensors angles of the electric motor.

To shift all the halls, you must press the right button of the On-board computer, enter the shift angle, press the right button again. The value will be reset and the angle of all halls will change to the specified value. You can change the angle of the hall shift in the opposite direction by setting a negative value.

Reset angles — reset of all Hall sensors angles. Select of values On and Off.
Integration threshold — analogue of Hall angles for sensorless engine control mode, in volts (V).
Hall adjust Ki — the meaning of the coefficient is to find the midpoint of the position of the Hall sensors when adjusting them. Values from 0.02 to 5.00, in increments of 0.02. If the value of the coefficient is too small, then the tuning process will end before the midpoint is determined. If the value of the coefficient is too large, then the setting will not be completed and will stop by timeout, because the midpoint will not be found due to the angles changing too often.

Hall table

The Controller > Motor Setup > Hall table menu section shows the Hall indices and Hall angles for the two directions of rotation of the electric motor. These indices are used for the internal operation of the Controller.


Motor parameters

Items in the Controller > Motor setup menu section allow you to configure the parameters of the electric motor.

In the kit:

  • CAN-cable 1,2-meters length for connection to the On-board Computer.
  • Phase wires.
  • Battery wires
  • Hall sensors wire.

Phase, battery, and Hall sensors wires are supplied with connectors, depending on the type and specification of the controller in the order.

Optionally you can order:

  • САN-cables 0,3 and 2 meters length.
  • Controller-side inputs for connection throttle, brakes levers directly to the Controller.
  • PWM/PAS wire for connection PAS, fans for cooling or brake lights.

Connection diagram

First, connect the three phases of the electric motor. It does not matter in which order and by which color you connect the phases, the controller will automatically detect them during auto-setup. Next, connect the hall connector as shown in the diagram below. You also need to connect the throttle lever and battery power. We also recommend connecting the brake levers, as their actuation turns off the motor. A simple rule — in any incomprehensible situation, press the brake.

When the power is turned on for the first time, the controller will start automatically. To enable/disable the controller, you must connect an external switch according to the diagram or configure the button located on the back of the On-board computer in the menu Devices > Controller > Extra parameters > Disable button.

You can find the wiring diagrams of the other devices on this link. By default, all peripherals (throttle, brake, switches, etc.) are connected into ports located on the backside of On-board computer. To access the ports, you need to unscrew five screws and remove the plastic cover. For connection, use PHD 2.0 connectors and crimp pins, which are included in the kit. If you do not have a crimping tool such as Crimper SN-2549, you must order “Crimped wires for display”. The On-board computer is connected to the controller with one CAN-wire 1.2 meters long, which is included in the controller kit. Be careful, the CAN-wire from the Controller is connected to the SYSTEM connector on the backside of the On-board computer.

If you want to connect peripherals directly to the Controller, you need to order “Control-side inputs”, in the diagram below this switching option is designated as “Alternative connection”. You can also use a mixed connection, for example, connect the throttle lever to the On-board computer, and the brake lever to the Controller.


Connecting multiple controllers

If you want to connect two or more Controllers, you can use a CAN splitter with four ports (purchased separately) or a lighting controller uLight, which also has three own CAN ports. The On-board computer supports the connection of up to eight Controllers.

For example, for a two-motor connection scheme, which is used on all-wheel-drive electric scooters, in addition to the second controller, you will need a CAN-splitter and one more CAN wire (there are 2, 1.2, and 0.3 meters long). Each Controller has a standard CAN-wire 1.2 m long. These wires from both controllers must be connected to a CAN-splitter, and from it one CAN-wire connects directly to the On-board computer. In the On-board computer, you can configure both controllers are separate.


Pay attention to the connection diagram. Do not disconnect power grounds when system wires are connected! First connect all power wires and only then CAN wires. When disconnecting the controllers, first disconnect all CAN wires and only then disconnect the power cables; it is also recommended to discharge the controller capacitors with a resistor or an ordinary light bulb.


How to start?

After you have connected the Controller and Controls according to the diagram, you need to configure the battery parameters. For this, go to the Settings > Devices section, select the Controller in the list of devices, then go to the Controller > Battery section and specify the supply voltage range. For a detailed description, see the section Battery.

After configuring the battery, you need to run Auto-setup in the Controller > Auto-setup menu section. Ensure that the phase and battery wires are well contacted and insulated before running auto-setup. Check that the Hall sensor wire connectors are fully inserted into the mating parts. For details, see the section Auto-setup. After auto-setup, you need to adjust the speedometer to display the speed correctly, see the section Speedometer setup.

Menu navigation

Use the On-board computer buttons to navigate through the menus. Left button — return to the previous menu or cancel editing. Right button — go to the menu section and confirm the parameter selection. The two middle buttons — to move up/down through the menu and select the value of the menu item.

Settings saving

In the menu item Controller > Save settings you can save all the settings made. Press the right button of the Onboard-computer and select On to save. If you do not save the settings, they will be reset after restart.

Auto-setup

The auto-setup function in the Controller > Auto-setup menu section allows you to automatically set up the electric motor, throttle, and brake levers.

The auto-setup menu starts the subprogram and shows only the process. All settings are saved under Controller > Motor setup. After restarting the Controller, all switches will be in the Off position.

Once you have specified the battery supply voltage in the Controller > Battery section, you can proceed to calibrate the motor and levers in the Auto-setup section.

Before auto-setup the angles, we recommend specifying the correct number of motor pole pairs in menu item Controller > Auto-setup > Pole pairs. See Motor information for this number for the most popular motors. If your motor is not on the list, check with the manufacturer or search the Internet for information.


Be careful! Before running autotuning, check that the drive wheels of your e-bike are not touching the surface and that the pedals (if equipped) do not touch anything when spinning. When adjusting the Hall sensors, the motor rotates in both directions, be careful and do not stand near the bicycle pedals. The motor will rotate five times, once when the motor is detected and four times when correcting the angle.


If you have a throttle lever and an analog brake connected, then you need to enable Full Setup, and follow the instructions on the On-Board computer screen. The corresponding menu items will indicate when to press and release the throttle or brake lever.

If only one throttle lever is connected, you must independently turn on the items step-by-step: Throttle, Motor, Angle correction. When you enable each of the menu items, the hints will be displayed. Auto-setup function Motor LR detects the inductance and resistance of the motor. You can see the measurement results in the menu section Controller > Motor setup, items Phase resistance, Inductance d and Inductance q.

If the motor is heavy and autodetect does not happen, you can gently push it with your hand or increase the tuning current in the Controller > Auto-setup > Setup current section, for example, twice. The setup current can be selected in the range from 2A to 50A, in increments of 1A.

If the motor is rotating in the wrong direction, go to Controller > Auto-setup > Spin direction and change the direction of rotation. You can choose from two options Forward or Invert. A similar setting is available in the Controller > Motor setup> Spin direction menu. It doesn't matter in which menu you make the setting, after saving, the direction of rotation will be reversed in both sections.

If an error occurs during autotuning, see the section Diagnostics of controller malfunctions. In the menu item Controller > Auto-setup > Control source you can select the sources of control for the Controller. See Control Source section below for details.

Firmware update

In the menu section Controller > Settings and Update, you can update the Controller's firmware, reset settings, import or export a configuration. You can upload all controller settings to a microSD card. The created file with the name NCconf.cfg - NCconf9.cfg you can open with the “Notepad” program, see all your settings, make any changes, save. Likewise, you can import a previously saved configuration into the Controller. Trip computer settings cannot be exported or imported. On-board computer settings can be exported and imported in separate sections of the Onboard computer menu. This function is only available in the On-board computer firmware version 0.7B and higher.

Import config. — loads the settings from the file NCconf.cfg - NCconf9.cfg up to a maximum of 9 different configurations, choosing a file number from 1 to 9. After a successful import, error messages may appear in the message, this means that not all the settings have been imported. In this case, it is advisable to check the downloaded settings with the original file by opening it in Notepad.

Export config. - saves the settings to the NCconf.cfg - NCconf9.cfg file up to a maximum of 9 different configurations, choosing a file number from 1 to 9.

Reboot — restarts the device. If the settings have not been saved, they will be reset.

Reset Wh usage — resets the accumulated number of Watt-Hours in the controller. This indicator is displayed in the statistics of the On-board computer, see section Statistics.

Reset stats — resets mileage in kilometers.

Load defaults — after a reset, the default settings are loaded but not saved. If you restart the Controller without saving after a reset, the previous settings will be loaded.

Erase data storage — This function may be needed for the correct firmware update, rollback to default settings, in a situation where user actions lead to incorrect operation of the Controller. If the controller has stopped saving the settings, do a reset, wait 3 seconds, and try to save again.

Update firmware — starting the firmware update process. You can download the current firmware version and read the rules of update in the Firmware section. To update, download the firmware file to the root directory of the microSD card with the Fat/Fat32 file system. Insert the card with the contacts facing up into the slot on the On-Board Computer and select On . When the update process is complete, a message appears on the screen Update finished. Press the left button and check the update version under Controller > Device Information.

Control modes

In the menu section Controller > Control modes you can configure and save three presets of the parameters of the electric motor and switch between them using a 3-position switch or buttons on the On-board computer. The currently active mode number is displayed at the top of the main screen. After setting, it is necessary to activate the modes in the menu item Controller > Additional modes > Enable additional modes by setting the value On. In the same menu Controller > Additional modes you can make detailed settings for each mode (see the section Additional modes).

If there is no speed switch, then mode 1 is the default. If the switch is connected to the On-board computer, it is necessary to configure the On-board computer buttons in the On-board computer > Button settings menu. See section Buttons setup.

Modes setup

The # Current mode line displays the currently selected control mode. List of possible options:
N — neutral.
S1 — speed 1.
S2 — speed 2.
S3 — speed 3.
RV — reverse.

Four parameters are used to configure each mode:
Phase — the maximum value of the phase current, in Amperes (A). Select of values from 0A to 500A, in increments of 2A. When setting, consider the maximum phase current of your controller type. In most cases, we recommend specifying the value of the phase current 1.5-2 times higher than the battery current.

Battery — the maximum value of the battery current, in Amperes (A). Select of values from 2A to 400A, in increments of 2A. When setting up, consider the capabilities of the connected battery and the maximum battery current of your controller type.

Power — maximum power (discharge) of the battery, in kilowatts (kW). Select of values from 0.00kW to 30.0kW, in increments of 0.1kW. Set to 0.0kW to disable the power limiting limit.

Speed — maximum speed in percentage (%). Select of values from 4% to 150%, in increments of 2%. The value of this parameter determines the percentage of speed depending on the reference speed (see section Speedometer setup). A speed value over 100% activates the field weakening mode, which allows the motor to accelerate above the supply voltage. (see section Field weakening setup).

Electric brake setup

Braking phase — the value of the phase current of braking by the motor, in Amperes (A). Select of values from 0A to 500A, in increments of 2A. For braking to zero, it is recommended to enable Active braking in the section Controller > Control. When using the switch brake, lower brake current change speed makes recuperation more smooth.

Braking phase at speed control

Braking ph. at speed — phase braking current during speed control, in Amperes (A). Select of values from 0A to 500A, in increments of 2A. This function allows you to slow down when you reset the throttle stick. Works only with Direct Drive motors, without a clutch.

Also to use this mode should be selected: Speed or Speed and Torque mode in the Controller > Control > Throttle Mode menu item. In the menu item Controller > Control > Speed lim. at 0% throttle enable the speed limit at 0% throttle (optional), enable if you need braking with completely released throttle.

Regenerative braking setting

Braking ph. at 0% throttle — phase braking current with the throttle handle released, in Amperes (A). Select of values from 0A to 500A, in increments of 2A. This function allows regenerative braking to be initiated when the throttle is released.

This function will be active if additional modes are disabled in the Controller > Advanced modes menu section or if, with activated additional modes, in one of the menu sections Mode S1, Mode S2 or Mode S3 in menu item Braking ph. at 0% throttle was setup is 0A.

Reverse setup

Speed reverse — reverse speed, in percentage (%). Select of values from 2% to 150% , in increments of 2% . The value of this parameter determines the percentage of speed depending on the reference speed (see section Speedometer setup). A speed value over 100% activates the field weakening mode, which allows the motor to accelerate above the supply voltage (see section Field weakening setup).

Phase reverse — the value of the reverse phase current, in Amperes (A). Select of values from 10A to 500A, in increments of 2A.

Field weakening setup

Field weakening — the magnitude of the field weakening current, in Amperes (A). Select of values from 0A to 500A, in increments of 2A. This setting allows you to increase the maximum motor speed and depends on the supply voltage, in any case, the speed will be no more than the maximum supply voltage (Vmax) of the controller (95V limit).


The current of weakening creates a field that acts against the field of the permanent magnets. The superposition of these fields creates an equivalent field that is below nominal. The attenuation efficiency depends on the parameters of the motor. The best results can be obtained with IPM motors.


To set up the weakening, you need:

  • for one of the control modes in the section Controller > Control modes specify a speed value greater than 100%, for example, Speed 3 is 120%.
  • set the weakening current value in the section Controller > Control modes, you can start from 30A.

Field weakening is activated when the maximum speed is reached, the Controller adds weakening current, limiting the phase current and weakening current specified in the control mode. That is if the effective phase current is 70A, and the weakening current is set to 30A, then a minimum of 100A must be specified in the phase current settings. If the phase current increases to 80A, then only 20A will remain for weakening because 80A + 20A = 100A.

Also, the Controller will limit the speed of rotation of the motor so that its effective EMF does not exceed the maximum supply voltage of the controller (not the battery). If the motor starts twitching on the suspended wheel, then it is necessary to reduce the weakening current.

Current change speed

# Current change speed.

  • acceleration, select of values from 50A/s to 50000A/s, in increments of 100A/s.
  • braking, select of values from 50A/s to 50000A/s, in increments of 100A/s.
  • shutdown, select of values from 50A/s to 50000A/s, in increments of 100A/s.

Three parameters determine the rate of change of the current (smoothness). The higher the value, the faster the current build-up in the motor will occur. For conventional brake levers, it will be useful to reduce the parameter braking for a smoother activation of the regeneration. If the throttle response seems too slow, you need to increase the parameter acceleration. The parameter shutdown determines how quickly the current drops after throttle and brakes are released.

Advanced control modes

In the menu section Controller > Advanced modes enables the control modes and activates the advanced settings for each of these modes.

To activate the control modes, select Controller > Advanced modes > Enable add. modes and to set On.

In the menu Controller > Advanced modes > Neutral by default you can activate the neutral mode (N) when the controller starts up, which will be active until one of the speed modes is activated. In a neutral mode, only the electric brake operates, throttle and PAS are disabled. This mode is recommended for use with speed buttons (not a switch). The function does not work with a 3-position switch (functions of the S1of3 and S3of3 ports in the Controller > I/O configuration menu). ​


Each mode has its own section in the Controller > Advanced modes > Mode S1, Mode S2, Mode S3 with the following settings:

Throttle mode — selection of the operating mode of the throttle lever, read more in the section Throttle control mode setup.

Acceleration lim. and Deceleration lim. — are specified in ERPM/s, select of values from 0 ERPM/s to 500000 ERPM/s, in increments of 200 ERPM/s . These settings allow you to limit the speed of acceleration or deceleration of the motor, it is convenient to use on slippery surfaces. For setting go to the Controller > Status flags section, in this menu there are two parameters that register the maximum acceleration and deceleration — Max acceleration and Max deceleration. Reset the values of these parameters in the same section of the menu, then you need to ride your e-bike in order to register the current dynamics of acceleration and deceleration. You can use these values as a reference and decrease them if you need to limit change speed. If the type of surface changes, for example, it becomes too slippery, then these values can be reduced until it becomes comfortable to catch the moment when the wheel loses traction.

Braking ph. at 0% throttle — phase braking current with the throttle handle released, in Amperes (A). Select of values from 0A to 500A, in increments of 2A. This function allows regenerative braking to be initiated when the throttle is released. If 0A is specified or additional modes are disabled in the Controller > Advanced modes section of the menu, then for the recuperation level will be used value from menu item in the Controller > Control modes > Braking ph. at 0% throttle menu item.

Revers — reverse gear activation when the control mode is selected. Select of values On or Off.

Cruise — activation of the cruise function. Select of values On or Off. Convenient to use with cruise mode Allow Throttle hold in the menu section Controller > Control > Cruise > Cruise to enable cruise in certain modes. See section Cruise control setup.

Disable motor — completely disables motor control. Select of values On or Off.

Disable throttle — disable throttle control. Select of values On or Off.

Active braking — allow the brake to use the battery for stopping. Select of values On or Off.

Reverse on brake — after stopping, pressing the brake lever again activates reverse speed. Select of values On or Off.

Speed lim. at 0% throttle — allows limiting the speed when the throttle lever is released. Select of values On or Off. Selecting Off disables motor control when the throttle is released.

Disable PAS — disables the Pedal Assist. Select of values On or Off.

PAS Scale — extra PAS multiplier for tuning, decreases PAS signal for smoother control on high power modes. Select of values from 1% to 100%, in increments of 1%.

Control

In the Controller > Control menu section you can setup setting the engine controls, throttle levers, torque and PAS sensors, cruise control.

PAS and Torque sensor setup

In the menu section Controller > Control > Pedal Assist System you can set up the Pedal Assist System (PAS), which connects the electric motor when pedaling.

ЧTo be able to connect the PAS system, it is necessary to order the PWM IO/PAS cable as an option. The PAS system connects to the Controller via the PWM IO/PAS wire to the P1/P2 ports of the USB/PWM connector. When using a SEMPU pressure sensor, an additional signal output from the TH port of the connector Control is required.

You can look at the connecting methods of various PAS systems at Connection diagram.

The PAS, unlike the Torque sensor, controls the throttle by frequency and not by the force of rotation. The PAS setup menu consists of the following items:

PAS — selection of pedaling assistant type PAS sensor or Torque sensor. If there is no PAS system, select Disabled.

PAS connection — 1-wire or 2-wire connection option, two wires are used for the angle sensor (encoder).
Invert PAS — change of direction in case of 2-wire connection. Select of values On or Off.
PAS poles — number of impulses per pedal revolution. Select of values from 1 to 200, in increments of 1.
PAS min. freq. — the minimum pedal speed (cadence) at which the motor starts, RPM. Select of values from 1 RPM to 500 RPM, in increments of 1 RPM.
PAS max freq. — the maximum pedal speed (cadence) at which the motor starts, RPM. Select of values from 10 RPM to 1000 RPM, in increments of 5 RPM.

# PAS freq. — the value of the signal coming from the PAS in real-time.
PAS timeout — the time after which the motor turns off after stopping pedaling, in seconds (s). Select of values from 0.02s to 5.00s, in increments of 0.02s.
PAS filter — smoothing the control signal for smoother operation, in hertz (Hz). Select of values from 1 Hz to 100 Hz, in increments of 1 Hz.
PAS min out — minimum control level when PAS is running, in percent (%). Select value from 0% to 100%, in increments of 1%.
PAS max out — maximum control level, in percent (%). Select of values from 0% to 100%, in increments of 1%. By analogy with the “pressed” throttle, PAS sends a signal within the specified limits.

Further in the menu are the settings related to the pressure sensor (Torque sensor).

Pressure scale — in Newton-meters/volts (Nm/V). You can calibrate by placing a load on the pedal and calculate the torque on the shaft through the lever. Select value from 0.0 Nm/V to 100.0 Nm/V, in increments of 0.5 Nm/V.
Zero pressure — zero pressure, in millivolts (mV). Select of values from 0mV to 10000mV, in increments of 10mV.
Protection pressure — switching off the pressure sensor when the threshold of the specified value is exceeded, in millivolts (mV). Select of values from 0mV to 10000mV, in increments of 100mV.
Torque averaging — period for which is torque value updated. Measured in half turns (turn/2). If the torque sensor measures only one pedal, then the period must be a multiple of two. Select of values from 1 turn/2 to 20 turn/2, in increments of 1 turn/2.

# Torque — shows the current torque at the sensor, in Newton-meters (Nm).

# Human watt — shows the average power you develop when pedaling, in watts (W).
Human watt min — the minimum power you develop to activate the motor, in watts (W). Select of values from 0 W to 500 W, in increments of 10 W.
Human watt max — the maximum power for 100% activation, in watts (W). Select of values from 0 W to 1000 W, in increments of 10 W.

Torque min — the torque at which the throttle signal starts to increase, Newton-meters (Nm). Select of values from 0 Nm to 100 Nm, in increments of 2 Nm. All values less than this level is 0% of throttle.
Torque max — the torque, which limits the level of 100% throttle, Newton-meters (Nm). Select of values from 0 Nm to 300 Nm, in increments of 2 Nm.
Instant Torque — allows torque sensor activation without rotation. Select of values On or Off. The pressure sensor also includes frequency configuration and output level configuration as well as the usual PAS.

Remote control

The Controller > Control > RC Control menu section allows you to configure the remote control of the Controller using an external RC receiver.

Input for radio control via PWM (PWM), connects to the P1 port of the USB/PWM connector on the Controller board. To activate the function, select the PWM value in the P1 Input Mode menu item.

The # Input Freq. and # Width menu items show the current signal value in hertz (Hz) and milliseconds (ms), respectively.

In the menu item Function selects the control function — Off, Throttle, Brake or Throttle and brk.


Adjust the throttle and/or brake range as indicated by the signal.

# Throttle range
Throttle min — minimum throttle value, in milliseconds (ms). Select of values from 0.00 ms to 10.00 ms, in increments of 0.01 ms.
Throttle max — maximum throttle value, in milliseconds (ms). Select of values from 0.00 ms to 10.00 ms, in increments of 0.01 ms.

# Brake range
Brake min — minimum brake value, in milliseconds (ms). Select of values from 0.00 ms to 10.00 ms, in increments of 0.01 ms.
Brake max — maximum brake value, in milliseconds (ms). Select of values from 0.00 ms to 10.00 ms, in increments of 0.01 ms.

Cruise control setup

In the menu section Controller > Control > Cruise you can set up the cruise control function. After connecting buttons or switches for cruise control to the ports of the Controller or Onboard Computer, you need to configure the functions that relate to cruise control:

CRe — cruise activation.
CR+ — increase cruise speed (when active).
CR- — decrease cruise speed (when active).
CRr — restoring cruise (turning on the last saved speed).

For more information about configuring these functions, read the I/O port configuration section below. If the cruise control button is connected to the On-board computer, then you need to configure it in the Buttons setup section.

In the Cruise menu item, you can select several control modes:
Disabled — cruise control disabled.
Button — activation of cruise control at the push of a button. The response time of the button is determined by the parameter Cruise EN time.
Switch — activation of cruise control by turning on the switch, time is not used.
Throttle hold — activation of cruise control by holding the throttle for a certain time in one position. The response time is determined by the parameter Cruise EN time. The accuracy is set by the parameter Cruise by throttle in percent (%). Select of values from 1% to 30%, in increment of 1%. Accuracy is essential, as the throttle lever moves slightly during the ride due to shaking. The default is 2%.
Allow Throttle hold — similar to the previous mode, with the difference that to activate the cruise control, you must additionally press the cruise button.

Next are the menu items for setting the cruise:

Cruise restore — this function activates the last saved cruise speed. To enable, select the CRr function when configuring I/O ports. The function can be deactivated by selecting the parameter Disabled.

Cruise EN time — setting the cruise activation delay in seconds after enabled button (s). Select of values from 0.25s to 30.00s, in increments 0.25s.

Cruise level — selects what speed cruise will use:

  • Throttle — speed depends on the position of the throttle lever, turns on instantly.
  • Speed — cruise enables when Safe acceleration reached after that uses current speed as a reference.
  • Mixed — if controller cant use speed reference, uses throttle value.

Cruise smoothness — this setting limits acceleration during cruising so that there are no jerks, measured in electrical revolutions per minute per second (ERPM/s). To get the value in rpm, the ERPM/s value must be divided by the number of pole pairs of the electric motor. Select of values from 0 ERPM/s to 50000 ERPM/s, in increments of 50 ERPM/s.

# Used for cruise activation:
Safe acceleration — limits the acceleration at which the cruise is activate, for example, to prevent it from engaging when accelerating, in electrical revolutions per minute per second (ERPM/s). Select value from 100 ERPM/s to 10000 ERPM/s, in increments of 100 ERPM/s.
Min. speed — speed below which you can not activate cruise or recovery, in kilometers per hour (km/h). Select of values from 3 km/h to 127 km/h, in increments of 1 km/h.

Additionally, to control the cruise, you can use the CR+ and CR- functions for the buttons, which adjust the cruise speed when it is active.

What actions disable cruise control:

  • pressing the brake, analog or digital.
  • repeated throttle press.
  • if a switch is used — when it's disabled.
  • reverse enable.

Throttle and brake curves setup

In the menu section Controller > Control > Throttle/brake curves you can set up the behavior of the throttle and brake levers. In Throttle preset and Brake preset menu items you can select one of the typical settings, select one of the throttle or brake presets, and press enter, the preset will be loaded.

You can select the following types of throttle and brake presets:

1-6 — midpoints, in percentages (%). Select of values from 0% to 100%, in increments of 1%.
End — end point, in percentages (%). Select of values from 0% to 100%, in increments of 1%.

You can also manually edit the value of each point in the loaded preset.


Control source

The controller supports the connection of controls (throttle, brake, switches, and buttons) to the Controller, On-board computer, ulight board, or mixed connection when one part of the periphery is connected to the Controller, and the second part to the On-board computer, or to ulight and On-board computer. This is necessary in the case of Tork/PAS sensor configurations in the Controller + throttle lever in the On-board computer. In the menu item Controller > Control > Control Source you can set up the control source of the Controller`s.

Select of control options:
Auto — all sources will control the Сontroller. Built-in and external, connected via CAN bus (for example, On-board computer or ulight).
Embedd — only what is connected directly to the Сontroller.
Remote — control only via CAN bus (via On-board computer or Microlight).
Disabled — disables any control of the Controller.


Throttle control mode setup

The menu item Controller > Control > Throttle mode you can set up throttle lever mode.

Three throttle modes options are available:
Speed — a similar mode is used in Infineon controllers and non-programmable low-cost controllers and is characterized by the use of maximum current to reach a given speed. In this mode, the maximum thrust is used until the desired speed is reached, the thrust is not regulated by the throttle grip.
Torque — in this mode, the throttle controls phase current, the thrust is limited by the angle of rotation of the throttle.
Speed+torque — combined mode (as Kelly), similar to the operation of the gas pedal in a car with an internal combustion engine.

In the case of selecting the Speed+torque mode, pressing throttle to 50%, when achieved 50% speed, the current consumption will be reduced to hold speed. The acceleration current will also be proportionally lower.

Throttle and brake voltage range setup

The menu items in the Controller > Control section allow you to set the voltage ranges of the throttle and brake grips.

Currently, voltage settings for all throttles and brakes are common.
# Throttle — shows the voltage of throttle grip connected to the controller, in volts (V).
Throttle min and Throttle max — range of the throttle grip, in millivolts (mV). Select of values from 0 mV to 15 000 mV, in increments of 10 mV. If the maximum value is exceeded by 5%, protection against a broken throttle grip will be activated. If the range is incorrectly set, then when you fully press the throttle grip, the electric motor will turn off, in this case, you need to increase the range value.

# Brake — shows the voltage of the brake connected to the controller, in volts (V).
Brake min and Brake max — range of the analog brake lever, in millivolts (mV). Select of values from 0 mV to 15 000 mV, in increments of 10 mV.

Brake button power — braking force when pressing the brake button relative to the phase braking level, in percent (%). This setting allows you to adjust the level of braking force with the brake levers with integrated brake buttons.
Invert brake — inverts the voltage value from the built-in brake lever. Select On to enable. It is useful to enable when the voltage brake lever with reverse voltage is connected to the On-board computer and you want to use the value Auto in the menu item Controller > Control > Control source. The digital brake grip (i.e. button) connects to the On-board computer, see section Buttons setup.
Active braking — enables brake to use the battery for stopping. Select of values On and Off.
Brake at overheat — enables full torque braking when motor overheated. Select of values On and Off.
Reverse on brake — after stopping, pressing the brake lever again activates reverse. Select of values On and Off.

Setup 100% speed value

The menu items in the Controller > Control section allow you to adjust the 100% speed level. The maximum speed in the field weakening mode is 150%.

Speed ref. filter — filter mode selection. Select of values OFF, Linear, Quadratic, Cubic. For the control modes Speed and Speed+torque, a speed reference filter is applied, for a smoother response to the throttle change. The filter algorithm calculates the difference between the previous speed request and the current one, multiplies the error by a power of 1,2,3 (linear, quadratic, and cubic, respectively), and multiplies by a factor. The resulting value is used as the cutoff frequency of the low-pass filter. The larger the change, the sharper the response to it.

Filter factor — sets the filtration factor. Select of values from 0 to 30000, in increments of 100.

Speed mode allows you to select the level of 100% speed and what it depends on:

  • OFF — completely disables speed control PID.
  • Middle U bat — the average value between the minimum and maximum voltage of the battery settings used as speed reference, depending on motor kV.
  • U supply — supply voltage used as speed reference, depending on motor kV.
  • Ref. speed — speed in km/h, is set by parameter Reference speed. The speed value is taken from the motor or from an external speed sensor connected to the controller.
  • Ref. ERPM — speed in motor electric RPM, is set by parameter Reference speed.

Minimum speed — in electrical revolutions per minute (ERPM). Select of values from 0 ERPM to 100000 ERPM, in increments of 100 ERPM.

Speed lim. at 0% throttle — enables limiting the speed when the throttle grip is completely released. Select of values On and Оff. Selecting Off disables motor control when the throttle is released.

Motor setup

The Controller > Motor Setup menu contains all settings related to electric motor operation parameters.

Motor temperature sensor

In the menu section Controller > Motor setup > Motor t°-sensor you can select a temperature range in which a smooth power limit will occur (Delta °t parameter) and specify the maximum temperature (°t max).

°t max — maximum electric motor temperature, in degrees Celsius (°C). Select of values from 50°C to 200°C, in increments of 1°C.
Delta °t — the temperature value that is deducted from the maximum temperature (°t max), the resulting temperature value will be the beginning of the power limit, in degrees Celsius (°C). Select of values from 1°C to 100°C, in increments of 1 °C.

In the menu item Sensor type you can select the following types of temperature sensors that support the controller — KTY81(82), KTY83, KTY84, NTC10K (B:3950), NTC10K (B:3380), PT1000. To disconnect the temperature control, select the value OFF.

It is recommended to install a temperature sensor so close as possible on the stator windings, while not in contact with the stator iron. If you don't know what kind of sensor is in the motor, you can check all types of sensors and select the one that displays data the most closely to room temperature. The current measured temperature is displayed at # Value °t #.

The # °t R (+-10%)# menu item displays the resistance of the motor temperature sensor, with an accuracy of +/-10%.

Clutch

In the menu section Controller > Motor Setup > Clutch you can configure a smooth engine launch for soft engagement clutch or freewheel. Useful for gear motors or mid-drives. At the moment, the setting works well only in the control mode Torque, because the clutch there is always engaged. An alternative option is to configure the acceleration limit in the modes S1, S2, S3 in the menu section Controller > Advanced modes.

The parameter Mode determines the way of operation::
Accelerate — smoothly accelerates the motor until the load appears.
Accelerate and hold — in addition to the previous one, it applies weak torque to the motor after the throttle is released, this mode allows you to switch speeds at mid-drive systems without using the pedals.

# Phase amps
Start time — maximum time for soft start, in seconds (s). Select values from 1s to 20s, in increments of 1s.
Start current — phase motor current at which the load will be detected and the soft start is disabled, in amperes (А). Select values from 0.2А to 50.0А, in increments of 0.2А. This value must be higher than the phase current for specified acceleration of the motor without load.
Detection time — the time during which the load must be present, after which the soft start will be switched off, in milliseconds (ms). Select values from 10 ms to 1000 ms, in increments of 10 ms.
Acceleration — value in volts/seconds (V/s). Select values from 2V/s to 1000V/s, in increments of 2 V/s. The higher the value, the more you need to specify Start current, since the motor will consume more current during acceleration.
Hold (20%) and Hold (80%) — two parameters regulating the phase current supplied to the motor in the mode Accelerate and hold, in amperes (А). 20% — current at low speeds, 80% — current at about maximum speed. It is possible to determine the approximate values ​​by the no-load current of the motor. Select values from 0.2А to 50.0А, in increments of 0.2А.
Hold enable time — time through which after the throttle has been pressed, torque hold will become available, in seconds (s). Select values from 1s to 120s, in increments of 4s.

Hold time — the time during which torque will be applied after releasing the throttle, in seconds (s). Select values from 1s to 120 s, in increments of 1s.


Optimal settings for MAC motor: Accelerate, 15a, 50V/s, 200ms.

Hall sensors setup

Under the menu section Controller > Motor setup > Position sensors, you can find the menu items for configuring the Hall sensors of the electric motor.

Manual setup the Hall sensors angles

The value will be reset and the angle of all halls will change to the specified value. You can change the angle of the hall shift in the opposite direction by setting a negative value.

Reset angles — reset of all Hall sensors angles. Select of values On and Off.
Integration threshold — analogue of Hall angles for sensorless engine control mode, in volts (V).
Hall adjust Ki — the meaning of the coefficient is to find the midpoint of the position of the Hall sensors when adjusting them. Values from 0.02 to 5.00, in increments of 0.02. If the value of the coefficient is too small, then the tuning process will end before the midpoint is determined. If the value of the coefficient is too large, then the setting will not be completed and will stop by timeout, because the midpoint will not be found due to the angles changing too often.

Hall table

The Controller > Motor Setup > Hall table menu section shows the Hall indices and Hall angles for the two directions of rotation of the electric motor. These indices are used for the internal operation of the Controller.


Advanced Hall sensor settings

Further in the menu section Controller > Motor Setup > Position sensor there are items for additional setting of Hall sensors.

Sensor type — currently, by default, only one type of Hall sensor is available. Additional types of supported sensors will be added in future updates.

Sensor mode — this parameter is loaded at start-up and can be saved. At the moment, the Controller has the following motor control modes:
Sensorless — motor control using BEMF integration, parameter Integration threshold is used. It is rather insensitive to tuning, but more accurate tuning may be required for high-speed motors (such as RC). At the moment, the sensorless does not have a start-up algorithm, it works stably only at some speed. Hall setups start with sensorless mode.
Combined — start the motor on Hall sensors, then switch to sensorless mode, the threshold is determined by the parameter radians per second (rad/s) in the From hall to s-less menu item. Select of values from 0.00 rad/s to 2.00 rad/s in increments of 0.05 rad/s. To convert values keep in mind that 1 rad/s to RPM = 9.5493 RPM.

The controller power button is located on the back of the On-Board Computer. In the Controller > Extra parameters > Disable button menu item, you can select the way to turn on/off the Controller, which turns on when it is powers-up or the button contacts are closed. In the off mode, the controller consumes about 100 μA, so if you reconnect the power supply without discharging the capacitors, the controller may not start.

Selecting modes for Disable button:
None — the controller turns on when it is power-up up or when the power button is closed, does not turn off.
Switch — the controller turns on when the power button is closed (when EN shorted to GND), turns off when it opens.
Button — the controller turns on the button on the On-Board Computer, press it for 2 seconds, and release, to disable it, press and hold the button again.
CAN — the controller turns on when it is powers-up or the button contacts shorts, disables only when another device on CAN bus will send a request to disable. This function is used when there are several controllers on a system, where one of them is set to button or switch mode, and the other in CAN mode.

Wheel sprocket — the number of teeth of the wheel sprocket, similar to the setting Motor sprocket.

If you have a wheel motor, then in the section Controller > Motor setup you need to specify the number of Pole pair (divide the number of magnets by two). For gear motors or mid-drives, it is recommended to install an external speed sensor that connects to the Onboard computer or to any of the controller ports.

Master-controller

In the menu section Controller > Extra parameters > Master-controller you can enable the function of controlling other controllers from the current one. This setting is suitable for multi-motor configurations where control (throttle, brake and etc.) is connected into one of the controllers directly.


Other settings

Limit t° CPU — limiting the temperature of the processor, in degrees Celsius (°C). When the specified threshold is reached, the phase current will be limited. Select of values from 60°C to 105°C, in increments of 5°C.

Device ID — setting the Controller number in the CAN network. This number is displayed in the menu section Settings > Devices in front of each device that is connected to the network using the LEVCAN protocol. If, by default, your device number is 0, we recommend changing it to another number for the correct firmware update.

Prefix 1 and Prefix 2 — controller name setting for multi-motor configurations. Using the prefixes together or separately, you can specify where the electric motor that the Controller controls is located. The selectable values for each prefix are None, Front, Rear, Left, Right. To save the setting, go to the Controller > Save settings menu item and select On, then restart the controller. The prefix will now appear in front of the controller name in the Devices menu.

For example, you have a 2WD scooter and two 12F controllers, you need to distinguish them somehow in the Devices menu for easy setup. A controller for a front motor can be prefixed with Front, in which case the controller will be named Front Nucular controller in the Devices menu.

If you are using a 3WD drive or more, then both prefixes must be used for the controller name. For example, if the controller is driving a rear right motor, the setting will look like this: Prefix 1Rear, Prefix 2Right.

Hall input — this parameter allows you to check the functionality of the Hall sensors. There are three digits in this item, each shows the signal level, if you rotate the motor slowly by hand, all three digits should change. If none of the digits change, check if the Hall connector is connected or the ground may be broken. If one of the digits does not change - there is no contact or the sensor wire is broken. To check the contacts in the controller, disconnect the Hall connector and measure the voltages on the controller connector. There should be about 4V on the signal lines of the Halls, 5V on the power supply, and about 3V on the temperature sensor line.

Logger

In the Controller > Logger menu section, you can enable and configure the data logging during the operation of the Controller. This functionality is experimental, errors may occur. The file is saved in CSV format to an SD card inserted into the On-board computer. To view the file, you can use the service Datazap. The SD card must have a FAT32 file system.

Start logging — to start recording, select On and press the right button of the On-board computer. After that, the #State menu item will change to Waiting status. The recording will start automatically after pressing the throttle grip. If an error occurs during the recording process, you will see its code in the # Error code menu item. In case of an error, firstly, check that the SD card has the FAT32 file system, and secondly, that there is free space on the SD card for recording. Additionally, you can delete unnecessary files from the card. After that, restart the Controller and start recording again. If the error repeats, contact us through the website or chat technical support and report the error code.

Stop logging — stop recording, select On to end recording.

  • Manual — enable manual recording.
  • At start — recording starts automatically when the Controller is turned on.

Log time — two parameters of time for recording to choose from:

  • Time step — delta of time since the previous record.
  • Sys time — global time, which is incremented after the start of the controller.

Log rate — delay between records of values. You can choose either the number of PWM cycles (PWM1, PWM2, PWM5, PWM10), either time (1ms, 10ms, 20ms, 100ms, 1s, 5s, 10s, 30s).

Mode — recording mode selection:

  • Buffered — buffering and recording in segments.
  • Max rate — continuous recording mode.
