FAN OTEMP
ABB · ACS800
What does FF83 mean?
The temperature of the drive output filter fan in the ABB ACS800 (step-up drives) is excessive. This supervision (3.16 AW 4 bit 0) indicates potential overheating of the output filter components, which can lead to reduced lifespan, degraded performance, or failure of the filter.
Common Causes
- High ambient temperature around the drive or within the enclosure.
- Restricted airflow to or from the output filter fan due to blockages or debris.
- Malfunction of the output filter fan (e.g., not rotating, rotating too slowly, or in the wrong direction).
- Accumulation of dust or debris on the fan blades or filter heatsinks, reducing cooling efficiency.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Stop the ABB ACS800 drive and allow it to cool down to ambient temperature.
- 2
Check the ambient temperature around the drive enclosure and ensure it is within the specified operating limits for the drive.
- 3
Inspect the output filter fan to ensure it rotates freely, in the correct direction, and that air flows without obstruction. Clean any dust or debris from the fan blades and air vents.
- 4
Verify that the drive's cooling system (fans, heatsinks, air ducts) for the output filter section is clean and free of obstructions.
- 5
If the fan is not functioning correctly or is damaged, consider replacing the output filter fan assembly.
