PARAMETER RANGE DESCRIPTION
Sensor Enable On/Off When programmed On, the motor temperature cutback and the motor
MotorTemp_Sensor_Enable On/Off temperature compensation features are enabled. This parameter can be
OptionBits3 [Bit 1] usedonlyifatemperaturesensorhasbeenproperlycongured.
0x306C 0x00 The motor temperature cutback feature will linearly cut back the
current from 100% to 0% between the Temperature Hot and Temperature
Max temperatures. The motor temperature compensation feature will adapt
the motor control algorithms to varying motor temperatures, for improved
efciencyandmoreconsistantperformance.

Note: The industry standard KTY temperature sensors are silicon
temperature sensors with a polarity band; the polarity band of a KTY
sensor must be the end connected to I/O Ground (pin 7).
Sensor Temp Offset
-20 – 20 °C Often the sensor is placed in the motor at a location with a known offset
MotorTemp_Sensor_Offset -200–200 to the critical temperature; the offset can be corrected with this parameter.
0x304A 0x00 The parameter can also be used to correct a known offset in the sensor itself.
Braking Thermal Cutback Enable On/Off When programmed On, drive current and all forms of regen braking current
BrakingThermalCutback_Enable On/Off will be cut back based on motor temperature. All forms of regen braking
BrakingThermalCutback_Enable_ current (Regen_Current_Limit, Brake_Current_Limit, EMR_Current_Limit,
Bit0 [Bit0] Interlock_Brake_Current_Limit) includes emergency reverse braking,
0x386C 0x00 interlock braking, brake input braking, direction reversal braking, neutral
braking, and speed limit braking.
When programmed Off, only drive current (and not the regen braking
currents) will be cut back based on motor temperature.
If the vehicle has mechanical brakes, setting this parameter to On may
help reduce motor heating.

MotorTemp LOS Max Speed
100–3000 rpm When a Motor Temp Sensor Fault (fault code 29) is set, a LOS (Limited
MotorTemp_LOS_Max_Speed 100–3000 Operating Strategy) mode is engaged. The maximum speed is reduced to
0x308A 0x00 the programmed Max Speed in the operating mode (Max_Speed_SpdMx,
Max_Speed_SpdM, Max_Speed_TrqM) or to the MotorTemp_LOS_Max_
Speed, whichever is lower.
