F21 fault in 6RA22 DRIVE (850 AMPS)

We have changed the A2 card as well as the A1card but the problem is not resolved. We have checked the entire field system as well as the motor but unable to resolve. Can anyone suggest how to resolve this issue. ------------------------------------------------------------------------------------------ Split from 6 RA 22 F21 problem.
