    Default FR-SE - Over Voltage (Converter) Error

    Hi Brains trust.

    trying to resolve an intermittent error with the FR-SE-2 spindle drive.

    The drive is tripping out on over Voltage (Converter) somewhat randomly.

    A week or so ago, I was in the middle of a cut and had the spindle drive trip on over voltage.

    I checked the waveforms and found 1 Waveform missing so I have ordered replacement DK434 driver chips and installed it today.

    Waveforms looks fine, including the response times etc.

    I ran the usual warm up cycle and all went fine.

    Then while running a very light cut (3000rpm - 12mm tool - 0.1mm/tooth feed - 1mm stepover/ 4mm DOC, it tripped out again on over voltage.

    I reset it and reran the cut again (sped up through air cutting)and it tripped again.

    I dropped the spindle speed to 2500 and feed down a bit also and it managed to complete the cycle ~ 25 mins.

    Then while I was thinking about the next test to debug the problem (with the spindle stopped and in home position), the error occurred again with the spindle stationary.


    I've had a look around and can't seem to find much on this.

    Has anyone come across this error and resolved it or have any suggestions on where to look?



    Cheers

    Mick

    Replace all capacitors.

    I have only recently replaced them all. Maybe the joints weren't so great. Will revisit this as a starting point. Thanks mate.
