Cause : IGBT temperature comes when drive IGBT temperature is excessive due to high ambient temperature, block airflow or motor overload.

The fault code 42F1 in your ABB ACS560 drive indicates an IGBT temperature is excessive. IGBT stands for Insulated-Gate Bipolar Transistor, a critical component within the drive that controls power flow to the motor. A 42F1 fault signifies that the IGBTs are experiencing excessive temperatures.

1. Check ambient conditions.
2. Check air flow and fan operation.
3. Check heatsink fins for dust pick-up.
4. Check motor power against drive power.
