Over-current during constant speed operation
1. Short-circuit at motor output: Check for possible poor insulation at the output line.
2. Sudden increase in motor loading: Check for possible motor stall.
3. AC motor drive output power is too small: Replace the AC motor drive with the next higher power model.
Check drive rectifier & IGBT using multimeter.
Check wiring.
Check drive hardware using multimeter.
