Cause: IGBT overload comes when excessive IGBT junction to case temperature. This warning protects the IGBT(s) and can be activated by a short circuit in the motor cable.
A2BA warning on an ABB ACS880 drive indicates IGBT overload condition. This means the temperature of the Insulated Gate Bipolar Transistors (IGBTs) within the drive's power unit has exceeded a safe limit.
Solution:
- Check motor cable.
- Check ambient conditions.
- Check air flow and fan operation.
- Check heatsink fins for dust pick-up.
- Check motor power against drive power.
