The drive output filter fan has an excessive temperature. This supervision is active in step-up drives and indicates potential overheating if airflow is restricted, the fan is faulty, or ambient temperatures are too high, risking damage to the filter or drive.
Click steps to track your progress.
Stop the drive operation immediately and allow the unit to cool down completely.
Measure the ambient temperature to ensure it is within the drive's specified operating range.
Verify that the fan rotates in the correct direction and that air flows freely through the cooling fins and vents.
