Cause : IGBT temperature comes when IGBT temperature is excessive due to heatsink fins for dust pick-up or fan faulty.

The AE16 IGBT temperature fault in an ABB ACS880 drive indicates that the temperature of the Insulated Gate Bipolar Transistor (IGBT) module has exceeded the allowable limit. IGBTs are crucial components in drives, controlling the power delivered to the motor.

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