I've same problem too... I've checked r0947 = 22 and r0949 = 1 How could I checked the IGBT??? So,when this happen,can inverter fixed without repairing??? Thank you it means " DC link overcurrent condition = IGBT short-circuit " you can check it by cold testing procedure. Check attachment to test IGBT If IGBTs are faulty then it has to be repaired..
