All, While performing the Autotune P115 then selecting 2 motor magnetization. the drive begins its autotune, but from anywhere from 5 -15 seconds after it starts, it shows an F008 fault. I have monitored the DC bus and found that it drops below 550 VDC and the Amps (r34) are at 136%. The rectifier never trips with a fault. A brief history over the past few days: Cur, PER3, and 4 of the six thyristor blocks have been changed. The system has two braking units installed and both have been replaced. The inverter has had all control cards (IVI, CUVC, PSU, ABO, VDU) changed. With the motor (General Electric GEB20) disconnected from the circuit there are no grounding issues on either the drive or rectifier. The motor meggers above 2 Meg and continuity check with a multimeter shows 300k Ohms to ground. Any help on this would be appreciated.
