Check the cooling of the motor.
Check the motor load and drive
ratings. Check the wiring of the
temperature sensor. Repair wiring
if faulty.
Measure the resistance of the
sensor. Replace the sensor if faulty.
The CPTC-02 module indic-
ates overtemperature:
• motor temperature is
too high, or
• the thermistor is in
shortcircuit.
