    Default VF Schematics?

    Thanks for the advice on tapping polycarb.

    We're in the process of servicing our Vf-1, it experienced a bit of lightning related trauma. We found a blown fuse on one board, replaced it, and the machine ran fine for 3 or 4 days.
    Then we got an alarm for spindle running, when it clearly was not.
    Our spindle drive is a Magnetek GPD503 model DS308.
    The drive had no indicator lamps, nor display. This unit is no longer supported by Magnetek, but it is by Yaskawa, its original manufacturer.
    Yask rep said symptoms indicated failure of electrolytic capacitors on power board, as this board contains the power supply goodies that the control board needs. Changed all the electrolytic caps, no bad ones found.
    No change in symptoms.
    New alarm says low voltage AC in.
    AC voltage in verifies to be normal.
    If I had a real live schematic, we could trace some of this stuff.
    I bought a new set of service manuals from haas when we bought the machine, but they are quite generic, as they cover every single machine haas makes. (eyes rolling)

    That said, is anyone aware of more detailed service and repair documentation, service guy training materials, or...?

    thanks in advance

    Default magnetek drive update

    We received our rebuilt magnetek drive for our haas vf1 yesterday.
    It arrived on-time, pre-configured.
    20 minute install, and it works great!
