Examples of settings

In this section, we provide examples of various typical Controller settings and some non-obvious functions. The section is constantly being supplemented, if you have an example of your own settings of any function, you can send us a description to info@nucular.tech.

Regenerative braking setting

Regeneration allows you to brake with an electric motor and charge the battery. This function cannot be implemented on geared wheel motors.

There are two ways to enable regenerative braking:

Regenerative braking by separate thumb brake

This regenerative braking method uses a separate analog brake lever or thumb brake.

  1. First connect the thumb brake to the On-Board Computer to the BRK port or to the Controller to the Control port via the controller-side inputs wires (option) according to the wiring diagram.
  2. If you have already done a full auto-setup of all systems earlier, then go directly to step 6. If you connect the thumb brake after going through auto-setup, go to step 3.
  3. Go to the Controller > Auto-setup menu section, select On under Brake, then follow the on-screen instructions for Brake autodetection. After successful configuration, you will see an OK message. Then go to step 6. If errors occur during the auto-detect process (value P was frozen), go to step 4.
  4. Go to the On-board computer > Information, find the Brake V parameter and check that the voltage range of the brake lever changes when it is pressed and released from ~ 0.8V to ~ 4.2V. If the range does not change, then you connected the thumb brake incorrectly or it is not working properly. If the range changes, then go to step 5. If you connected the brake lever directly to the Controller, then its voltage range can be checked in the #Brake menu item in the Controller > Control menu section.
  5. Go to the Controller > Control section and in the Brake min item set it to 150mV more than the specified minimum value, and in the Brake max item set it to 150mV less than the specified maximum value. Then go to step 6.
  6. To set the regeneration level, go to Controller > Control modes > Braking phase and set up the level of phase current of braking. If you have a scooter, you can start with 20A, for an electric bike you can start with 50A, for a Sur-Ron with 70A. Next, test the settings and, if necessary, increase or decrease the phase current to achieve the desired result.

Keep in mind that recuperation will not be possible with a fully charged battery.

Regenerative braking by releasing the throttle grip

With this type of braking, recuperation is activated when the throttle lever is released. The effect is similar to driving an electric car using one gas pedal, when pressed, accelerate, when released, slow down.

  1. First, connect the thumb throttle or twist throttle to the On-Board Computer to the THR port or to the Controller to the Control port via the controller-side inputs wires (option) according to the wiring diagram.
  2. If you have already done a full auto-setup of all systems earlier, then go directly to step 6. If you connect the throttle lever and do not connect the brake lever, go to step 3.
  3. Go to the Controller > Auto-setup menu section, select On under Throttle, then follow the on-screen instructions for Brake autodetection. After successful configuration, you will see an OK message. Then go to step 6. Then go to step 6. If errors occur during the autodetect process, go to step 4.
  4. Go to the On-board computer > Information menu, find the ThrottleV parameter and check that the voltage range of the throttle stick changes when it is pressed and released from ~ 0.75V to ~ 4.35V. If the range does not change, then you connected the handle incorrectly or it is not working properly. If the range changes, then go to step 5. If you connected the throttle lever directly to the Controller, then its voltage range can be checked in the # Throttle menu item under the Controller > Control menu section.
  5. Go to the Controller > Control section and in the Throttle min menu item set it to 150mV more than the specified minimum value, and in the Throttle max item set it to 50mV less than the specified maximum value. Then go to step 6.
  6. In the menu item Controller > Control > Throttle mode select one of two throttle modes - Speed or Speed+torque.
  7. Next, under Controller > Control > Speed Lim. at 0% throttle, select On to enable the speed limit at 0% throttle for braking with the throttle lever released.
  8. To set the regeneration level, go to Controller > Control modes > Braking phase and set up the level of phase current of braking. If you have a scooter, you can start with 20A, for an electric bike you can start with 50A, for a Sur-Ron with 70A. Next, test the settings and, if necessary, increase or decrease the phase current to achieve the desired result.

Reverse setting

Keep in mind that the reverse function cannot be implemented on geared motor wheels. You can use several methods to engage reverse:

If desired, item 1 can be combined with other options to have several ways of reversing.

Switching on reverse with the On-Board Computer button

This method of switching on the reverse is the easiest to set up and is activated by one of the four buttons on the On-Board Computer.

  1. Go to the On-Board Computer > Buttons setup menu and select which of the four On-Board Computer buttons you want to assign the reverse function to. For example, to the first button.
  2. In Hot key 1 type menu item select the control signal type Button, and in the item Hot key 1 func. select the free number of the CAN input, e.g. CAN Button4.
  3. Save the settings in the menu item On-Board Computer > Save.
  4. Go to Controller > I/O Configuration to configure the reverse function for the selected CAN port. To do this, in CAN port4 menu item, select the RV (reverse) value.
  5. Save the settings in the Controller > Save settings menu item. The setup is complete, now you must press and hold the first On-board computer button for two seconds to activate reverse. When the function is activated, you will see the R icon at the top of the screen.

Switching on reverse with external button connected to the On-board computer

To use this method you need an external button or switch. To connect to the On-board computer, the wire must be crimped with pins according to the diagram and inserted into the PHD 2.0 connector, which are included in the package of the On-board computer.

  1. The wire from the switch must be connected to the rear panel of the On-board computer in ports I/O1 or I/O2.
  2. Next, you need to check the functionality of the connected button and the activation of the input by closing the contact. Go to the On-board computer > Information menu and press the button. Depending on which port the wire is connected to, the values in the menu items Input 1 function - Input 8 function will change from 0 to 1 when the button connected to the On-board computer is pressed. If the value does not change, then the signal does not come and it is necessary to check the correct connection, contacts in the connector, wire, and the button itself. If everything is OK, go to point 3.
  3. Let's assume you have connected the button to the Input 2 func., it is the IO2 input of the I/O1 port. Now you need to assign to this On-board computer input the number of the CAN input for CAN-bus control and select the control signal type. Go to menu item On-board computer > Buttons setup, and in the menu item Input 2 type, select the control signal type, e.g. Button, and in menu item Input 2 func. select a free CAN input number, e.g. CAN Button4.
  4. Save the settings in the menu item On-Board Computer > Save.
  5. Go to Controller > I/O Configuration to configure the reverse function for the selected CAN port. To do this, in CAN port4 menu item, select the RV (reverse) value.
  6. Save the settings in the Controller > Save settings menu item. The setup is complete, now you must press the button to activate reverse. When the function is activated, you will see the R icon at the top of the screen

Switching on reverse with external button connected to the Controller

This method requires an external button or switch. To connect to the Controller, use controller-side inputs wires (optional) with SM 2.54 3P connectors.

  1. The wire from the switch should be connected according to the diagram to one of the ports on the controller-side inputs wires.
  2. Next, you need to check the functionality of the connected button and the activation of the input by closing the contact. Go to menu Controller > I/O configuration > Port state and press the button. Depending on which port the wire is connected to, the values in S1, S3, RV, CR will change from 0 to 1 when a signal is applied. If the value does not change, then the signal is not coming and you need to check the correct connection, contacts in the connector, wire, and the button itself. If everything is OK, go to point 3.
  3. Let's assume you have connected a button to the RV input. Now you need to assign the reverse function to this port on the Controller. Go to Controller > I/O configuration and select RV for the Port RV menu item.
  4. Save the settings in the Controller > Save settings menu item. The setup is complete. Now you need to press the button to activate reverse. When the function is activated, you will see the R icon at the top of the screen. To disable reverse press the button again.

Switching on reverse by selecting the control mode with activated function "Reverse"

With this setting, reverse is activated when one of the four On-board computer buttons is activated in one of the control modes. To use this method it is necessary to activate the reverse function when selecting the control mode.

  1. Go to the Controller > Advanced modes menu and select one of the control modes S1, S2, S3 in which the reverse will be activated. For example, S2.
  2. Go to Controller > Advanced modes > Mode S2 to Reverse menu item and select On.
  3. Next, activate the advanced modes, for this, in the menu item Controller > Advanced modes > Enable add. modes, set the value to On.
  4. Next, you need to select which on-board computer button will enable Mode S2 and configure this function. Go to the Controller > I/O configuration menu section, select one of the CAN ports, for example CAN Port 1 and select S2 in this menu item.
  5. Save the settings in the Controller > Save settings menu item.
  6. Go to the menu item On-board сomputer > Buttons setup, select which On-board Computer button will activate Mode S2, e.g. second. To configure in the menu item Hot key 2 type, select the control signal type Button, and in the item Hotkey 2 func. select the number of CAN input previously configured in the controller — CAN Button1.
  7. Save the settings under the On-board computer > Save menu item. The setup is complete. Now you have to press the second button of the On-Board Computer to activate the control Mode S2 with activated reverse. When the mode is activated you will see the R icon at the top of the screen. To disable reverse you need to switch to another control mode, S1 or S3, which must be pre-set to other buttons of the On-Board Computer.

Switching on reverse by selecting the control mode with activated function "Reverse on brake"

To use this method it is necessary to activate one of the control modes with activated function Reverse on brake using one of the four buttons of the On-Board Computer. After activating this function, pressing the brake lever again after stopping will engage reverse.
