Cause : Excessive IGBT junction to case temperature.
This fault protects the IGBT(s) and can be activated by a short circuit in the motor cable.
1. Check motor cable.
2. Remove motor cable then run drive. If fault coming after remove motor cable then drive faulty, if fault not coming then check motor & motor cable.
