Bafang CAN basic settingsLink
Accessible from menu CAN Bafang settings
Consists of common settings section shared by all CAN Bafang motors. In the Advanced section, there are more configuration options that may not apply to all motors.
Read - reads the settings shown on the page.
Write - writes the modified settings to the motor.
Before making any change to these parameters, it is heavily recommended to first perform a Read and take note of all the parameters originally stored on the motor, as they will be lost after overwriting them. We recommend that you create a Profile on the app's Profile section to store the original settings, or if that option is not available, perform a Customer Support procedure from the app including all display and app logs in order to collect parameter values.
Controller settingsLink
Low Voltage Protection (mV)Link
Value to prevent battery voltage cutoff (most likely your battery will have a BMS that will shut off power when the voltage gets too low). If your battery shuts down before reaching this value you should increase it.
Some motors show unpredictable values and behaviour with this field. If you experience issues with low voltage protection, please perform a Customer Support procedure from the app.
Max Current Limit (A)Link
Represents the global current limit in ampere (A). This sets the power level that the drive unit will pull from the battery pack.
Current limit affects your bike power, as the following formula shows:
Battery voltage (V) * Currrent limit (A) = Power (W) (For example: 48V * 20A = 960W)
If you get Limited Current (A) error, it means you are outside your controller accepted limits. Following the example picture above you can set a value of maximum to 28A.
PolesLink
The number of pole pairs in the motor. This is a fixed motor characteristic that must match your motor specification.
This value should match your motor's factory specification. Setting an incorrect value may result in motor malfunction or incorrect speed readings.
MagnetsLink
The number of magnets used for speed measurement.
ThrottleLink
Start Voltage (V)Link
The throttle input starting voltage. The point at which the controller responds to throttle input. As you begin to roll on the throttle the voltage moves up from zero and when it reaches this voltage value the motor begins to turn.
Attention
Do not change this value unless you really know what you are doing. Too low and the display will throw an error as the motor will want to run continuously.
End Voltage (V)Link
The maximum throttle input voltage the controller accepts. Setting this correctly ensures your throttle response is linear and smooth throughout its full range.
Attention
Do not change this value unless you really know what you are doing. If you set it lower than maximum voltage your throttle may be detected, your throttle response may not be as linear or smooth as it could be.
Throttle limitedLink
Determines whether the throttle is limited to 6 km/h. If this setting does not work or cannot be changed, see the Throttle limited strategy.
Speed SensorLink
Dynamic Current (%)Link
The percentage of current dynamically adjusted based on speed sensor input. This setting affects how the motor responds to pedaling speed variations, providing smoother power delivery during acceleration and deceleration.
Higher values provide more responsive power adjustment, while lower values provide smoother transitions.
Ramp up (ms)Link
Controls how quickly the power ramps up when starting pedal assist. Lower values provide quicker power delivery, higher values provide smoother acceleration. Value is in milliseconds.
A lower value will give you a more responsive acceleration, while higher values reduce strain on the drivetrain and provide smoother starts.
Ramp down (ms)Link
Controls how quickly the power ramps down when stopping pedaling or reducing effort. This affects how quickly the drive stops after you stop pedaling. Value is in milliseconds.
Lower values make the motor cut power more quickly, higher values provide a more gradual power reduction.
Assist levelsLink
Limited Current (%)Link
The percentage of the current from the Max Current Limit (A). For example if your bike has 250W and you set this setting to 50% you will have 125W. If you set it to 100% you will have 250W.
Limited Speed (%)Link
The percentage of the speed limit.
