    Fadal 4020 Crackling noise in my Inverter transformer cabinet

    Hi Guys
    I have this intermittent "CRACKLING NOISE" in my electrical cabinet.
    On the Invert-er box it does show a red light on the Y delta
    and a yellow/red light on the servo light.
    But machine is running OK.
    Looking forward to your feedback.

    Check the connections for arcing. "Crackling" could be something as simple as a a piece of debris stuck in a cooling fan.

    Get someone else to run the control panel while you watch and listen.
