Motor Temp Hot
Cutback
1. The motor temperature reaches or exceeds the alarm temperature
set by the program, resulting in the reduction of current output
2. The motor temperature parameters are incorrectly set
3. If the motor does not use a temperature sensor, program
parameters "Temp Compensation" and "Temp"
Cutback must be set to OFF.
16
Motor Temp Sensor
Fault
1. The motor temperature sensor is incorrectly connected
If the motor does not use a temperature sensor, the programming
parameters are "Temp Compensation and Temp"
Cutback must be set to "OFF"
