Fardriver Inverter ND96850
This is the Fardriver inverter ND96850, that controls the main motor.
Fardriver is a very popular inverter due to its easy setup and still has a lot of advanced function.
It has an App where you can setup all parameters.
On youtube there are a lot of videos showing how it works.
This forum on facebook is also very helpful if you have any questions:

The current settings of the inverter are shown below.
QS180
– AngleDetect: Depends on the motor encoder type.
– PhaseOffSet: Comes automatically when doing an autolearning procedure. Some people adjust this with a few degrees.
– Motor Direction: 0 is clock wise, 1 is counter clock wise.
– Rated voltage: Given by the manufatura.
– MaxSpeed: Depends on your setup up and nominal battery voltage.
– MaxLineCurr: Means max battery current.
– ThrottleResponse: Linear or quadratic characteristic
– PhaseExchange: If you for some reason want to mount yellow phase wire on green terminal and green wire on yellow terminal.
– Weak Character: Fast or slow behavier of the field weakening control
– Throttle Dec Step: Range 8 – 224. 8 is slow 224 is fast. response.
– Throttle Low: Set to lowest voltage of the throttle signal from the throttle.
– TempSensor: Select the type of temperature sensor of the motor.
– PolePairs: Given by the manufactura.
– RatedSpeed: Given by the manufactura.
– RatedPower: Given by the manufactura.
– BackSpeed: Max reverse speed.
– MaxPhaseCurr: Max current to the stator of the motor. This current is propotional to the torque.
– Throttle Acc Step: Range 8 – 224. 8 is slow 224 is fast.
– BoostPhaseCurr: Max temporary current when Boost button is pressed.
– ECOAccCoeff:
– WeakResponse:
– Release Throttle:
– Throttle High: Set to highest voltage of the throttle signal from the throttle.
– Ratios in Speed: The amount of phase current in speed interval.
– LD:
– FAIF:
– LowSpeedLineRatio: Max battery current when in LowSpeed.
– LowSpeedPhaseRatio: Max stator current when in LowSpeed.
– LowSpeed: Max speed when in LowSpeed.
– LQ:
– LimitSpeed:
– MidSpeedLineRatio: Max battery current when in middelspeed.
– MidSpeedPhaseRatio: Max stator current when in middelspeed.
– MiddleSpeed: Max speed when in middel speed.
– StopBackCurr: Amount of brake current when Low Brake or High Brake is activated. To activate this function “Follow” needs to be set to correct value.
– Batt RatedCapacity:
FreeThrottle:
– Energy Regenerate:
Max regenerative current in different speed intervals. These are percentage of “MaxBackCurr”.
– MaxBackCurr: Max regenerative current.
– Brake Voltage:
– Boost Pin: Choose an input to use the boost function. Boost can activate a temporary over current limit “BoostLineCurr”, “BoostPhaseCurr” and “BoostTime”.
– SideStand Pin:
– Forward Pin:
– Highspeed Pin: Choose an input to activate HighSpeed.
– Charge Pin:
– Seat Pin:
– Switch Voltage Pin:
– BoostTime: Max boost time.
– HighLowSpeed: Function of high and low speed input.
– EmptyRun:
Gear: Choose default gear
Brake:
Park:
– Cruise Pin:
– Pause Pin:
– Backward Pin:
– LowSpeed Pin:
– Anti-theft Pin:
– SpeedLimit Pin:
– Repair Pin:
– BoostRelease:
– Puse:
– SlowDown:
“NormalResponse” means that the controller has tendency to maintain the speed, so it is slower to accelerate and slower to decelerate. It is cruisial to set this to “RaceResponse” for winch applications as it will cause big oscillations when set to “NormalResponse”.
Here you can activate “StopBackCurr” and “MaxBackCurr”.

OverVolProtect: Voltage when controller cuts off due to over voltage.
LowVolProtect: Voltage when controller cuts off due to under voltage.
MotorTempProtect: Max motor temperatur.
