ABB drive Bivactor 500 fault
I'm facing a fault in ABB Bivactor 500 servomotor drive. Its completely silent as shown in the attached images.
I've check controller card of the driver and I found that no voltage presence at its input port !..Then I tested the power supply board and checked the DC high voltages and found that is exist on the PWM transformer input but the Board does not out any DC voltage on the cable connector pins !.
Hence ,I'm conclude that the power supply board is broken , but I haven't the circuit diagram to follow up the fault and repair it !.
Please, Help me to determine the faulty component or send me the circuit diagram of this board..Hope to hear from you...Best regards
