Controller Parameters

controller paramaters.png

Rated Voltage

Displays the intended battery voltage e.g. 60V. 72V, 84V. This will depend on the update you have chosen 60V, 72V or 84V. 

Rated Power

Shows the rated power - indication - changing this number does not affect the motor and controllers power output. 

Phase Offset

Not in use - cannot be changed automatically calibrated.

MaxLineCurr (Maximum DC current in)

Maximum current into the controller from the battery - Stock battery should be set to 95A maximum third party batteries should be set to manufacturers specifications. Maximum DC current is 370A. Please adjust accordingly and if your battery struggles to provide the power required reduce this number. This may show as a sudden slow down, or a loss in power as the battery BMS either throttles, or shuts the power to the bike off completely. If this occurs you should give the battery time to cool down and adjust your settings downwards to account for this. 

MaxPhaseCurr  Maximum phase current

This is the maximum phase current available to the motor and can be set up to 800A.

Speed Coeff

Not in use automatically calibrated.

ThreshholdLow (Minimum Throttle Input)

The lowest point at which the throttle will engage (measured in volts). Use this to calibrate where the throttle comes on for your bike.  Measured in voltage we recommend making small changes and test the effect with the back wheel lifted. You can adjust this value to add dead banding on your throttle. **Warning adding too much deadland may make the throttle unpredictable when accelerating - Please adjust with care**

ThresholdHigh (Maximum Throttle Input)

The highest point of throttle output (measured in volts) The maximum voltage that can be supplied by your throttle. 

we recommend making small changes and test effect with the back wheel lifted. You can adjust this value to add dead banding on your throttle. **Warning adding too much deadland may make the throttle unpredictable when accelerating - Please adjust with care**

AccSensitivity (Throttle acceleration sensitivity) 

Throttle acceleration sensitivity setting from 5-224. A low number will mean a less aggressive feel on acceleration (lower number = lower sensitivity). This value is set to 224 by default and should be left as this. 

BackThrottle (Advanced Users Only)  Negative throttle adjustment

This works by slowing the throttle deceleration values of 0-7 - zero is normal while raising the number will increase the time it takes for throttle deceleration to come into effect after dropping the throttle. 

WeakRSP - Magnetic field weakening  

Reducing this number will effectively reduce the maximum motor RPM. The lower the number the higher level of magnet weakening is used. Set to zero by default values available 0-6 plus disable.  We would suggest using 0 as a preferred setting. 

SKP - (Advanced Users Only) PID controller response time 

We would suggest not changing this too much. Values available are 0-128. Standard Sur-Ron set up is 5. This changes PIDs to improve response time on the PID controller 0= very fast while 128 is slowest response time. 

Start/Mid/MAX KI - (Advanced Users Only) Motor Vibration Control

This is primarily used for other motors leave at default but if you are using a lower horse power motor, such as the standard Sur-Ron motor you can adjust this value upwards to control motor vibration.

 

Over Voltage Protection

This value is set via the firmware version you are using and depend on the voltage of your battery. Cannot be changed. 

 

Low Voltage Protection - (Low Voltage Cut-Off)

Dependant on user requirements set in volts. You should refer to the manufacturers specification on your battery. If you are using multiple different voltages please ensure to upload the correct hex file to your controller. There is a different software for 60 and 72v batteries and the low voltage for each should be set accordingly. 

Temperature protection 

Thermal protection for the ESC. When the ESC reaches 80 Degrees Celsius it begins to throttle performance until the unit cools. At 90 Degrees ESC will cut power until the temperature reaches 80 degrees and then operation can continue. These are hard limits and will not be adjustable.
