Cause : Safe motor temperature comes when the CPTC-02 module indicates overtemperature due to motor temperature is too high or the thermistor is in shortcircuit.

1. Check the cooling of the motor.
2. Check the motor load and drive ratings.
3. Check the wiring of the temperature sensor. Repair wiring if faulty.
4. Measure the resistance of the sensor. Replace the sensor if faulty.
