Name
Fault Descriptions Corrective Actions
Over current
Abnormal increase in current.
1. Check if motor power corresponds with the AC
motor drive output power.
2. Check the wiring connections to U/T1, V/T2,
W/T3 for possible short circuits.
3. Check the wiring connections between the AC
motor drive and motor for possible short
circuits, also to ground.
