PARAMETER VALUES DEFAULT DESCRIPTION
Braking Thermal Cutback
Enable
On/Off Off Sets whether the controller cuts back regen braking current if the
motor reaches the Temperature Hot threshold:
On = The controller cuts back current for all forms of regen
braking, including emergency reverse braking, interlock
braking, direction reversal braking, neutral braking, and
speed limit braking.
Off = The controller does not cut back regen braking currents.
Regardless of whether this parameter is on or off, the controller
cuts back on the drive current if the motor reaches the
Temperature Hot threshold.
Note: If the vehicle has mechanical brakes, turning this parameter
on might help reduce motor heating.
Temperature Hot 0-250°C 145°C Species the temperature at which the controller starts cutting
back current.
Temperature Max 0-250°C 160°C Species the temperature at which the controller cuts back all
current.
Motor Temp LOS Max Speed 0-100% 50% Species the maximum speed for a vehicle when the controller
generates a Motor Temp Sensor fault.
The value is a percentage of the active speed mode’s Max Speed
parameter.
When a Motor Temp Sensor fault occurs, the controller applies
a Limited Operating Strategy (LOS) by reducing the maximum
speed by the specied percentage.
