    DC 110KW Drive Problem

    Board went completely dead first, stone dead. Haven’t checked motor winding. Wonder why the original board totally died. Orange transformers just leaked probably due to over current. See picture

    DC 110KW Drive Problem

    Motor spec attached. The board went dead all of sudden. Transformers blown. New board comes on but when PB is pressed the Drive cuts the power to motor. And then will have to switch off the drive and switch back on for reset. Could it be field problem in motor? What tests can be done
