Can you anyone advice me on how to proceed with G201x power problem? 2 of my four G201x drives do not light up the power on LED. None of those 4 is operational any more. Steppers do not move, although two steppers driven by two drives which do light up the power on LED, have holding torque.
Is there any way to check the drives? Could this be capacitors on powerstage? I used power relays to swich on drives. Could that cause the trouble?
Thank you...
