    Hi Sir:

    Happy New Year.

    In relation a your problem:

    C29 error code is generating Emergency Stop signal:is generated Inmediately when the Voltage exceed aprox 180Vdc.
    The condition is general if the fault remain for over 45 seconds in Overload situation.By that reason the fault generated the signal forEmergency Stop.
    Chopper Resistance activaded when the Overload exceeds value de 148Vdc.

    1) Test the voltage in female Connector X1: Pin -1+24Vdc x2: Pin-2Emergency signal Stop.

    2) Test the voltage in Male Connector X3: Pin 1+120vDC Pin 2 Ground Pin 3 Control Signal: Chopper Resistor Pin 4-5 Not Used.
    Test the input of machine and power supply and step up or down depending of cases if Incresase or decresead Voltage, adjust Taps of Primary of Trafo.

    Let me know
    Blessing
