Over-current during steady operation (output current exceeds three times the drive’s rated current during constant speed).
corrective action
1. Short-circuit at motor output: Check for possible poor insulation at the output.
2. Sudden increase in motor load: Check for possible motor stall.
3. AC motor drive output power is too small: Replace the AC motor drive with a higher power model.
