Cause : Motor thermistor over-temperature comes when the th trip indicates that the motor thermistor connected to terminal 14 (digital input 5) on the control connections has indicated a motor over temperature. If digital input 5 mode (08.035) is 2 then a th trip is initiated if the feedback value is higher than Thermistor Trip Threshold (07.048).
- Check motor temperature.
- Check threshold level (Pr 07.048).
- Check thermistor continuity.
