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

An AE14 fault code in your ABB ACS880 drive indicates an excess temperature condition. This means the drive's internal temperature has risen above the acceptable operating limit.

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.
