    Default Yaskawa V74x VFD displays 00 RPM

    Hi all,

    Yesterday my spindle wouldn't start. I checked the VFD; the run light was flashing and the RPM displays "00".

    The fan runs on the spindle, but that's a different circuit. I checked voltages- all seems OK. Restarted several times, but no joy.

    Any thought?

    Thanks,
    Ron

    OK, found and downloaded the original parameter setup, and got it working...
