Cause: Motor temperature 1 comes when the thermistor protection module installed in slot 1 indicates overtemperature. This means the motor is getting too hot and needs attention.
A497 in ABB ACS880 drive indicates Motor temperature 1 warning. This means the temperature of the motor 1 has reached its warning limit.
Solution:
- 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 sensor if faulty.
