FF82
Choke Overtemperature
ABB · ACS800 Standard Firmware
What does FF82 mean?
The drive output filter (choke) has an excessive temperature. This supervision function is typically used in step-up drives and indicates potential overheating due to restricted airflow, a faulty filter fan, or high ambient temperatures, risking damage to the filter components.
Common Causes
- Choke (inductor) temperature exceeding safe operating limits.
- Overload current flowing through the choke.
- Insufficient cooling or airflow around the choke component.
- Faulty temperature sensor on the choke.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Stop the drive and allow the unit to cool down completely.
- 2
Measure the ambient temperature around the drive enclosure to ensure it is within specified limits.
- 3
Verify that the filter fan rotates in the correct direction and that air flows freely through the filter and drive vents.
