I have a tac 50 with a 1503, 633 fault. The drive is faulted (red led is on) and it won't reset with run fault code or manual. It thinks I lost a phase, but incoming power is good any suggestions. The drive is a 2407 with igbts. Any help is appreciated.

1503 is brake contact or failed to pick, Check BRKC relay and brake contractor auxiliaries. 633 is a V+ IGBT fault, usually a bad IGBT.
