What to do if SANCH S900-4T2.2G Inverter detects over current at output side?
- K
  Kyle BairdAug 10, 2025
  If the SANCH Inverter detects an overcurrent at the output side, take the following steps: 1. Verify that the motor's rated current matches the AC motor drive's rated current. 2. Ensure there are no short circuits in U/t1-V/t2-W/T3. 3. Confirm that there is no short circuit or grounding in the motor connection. 4. Make sure the screws are securely tightened to the AC motor drive. 5. Increase the acceleration time (parameters 1-09, 1-10). 6. Check that the motor is not overloaded.
