    So what do ya'll think? I do not have three phase power here and $40k to get it, well My little shop can't pull that off.

    Re: Hitachi VK45 won't run in AUTO mode

    Note: both my load and speed meter indicate when the spindle is running, they are both analog gages and my status screen only shows the last speed and direction command given.

    Cody, the problem stays with each board and does not move when the EPROM's are moved.

    Old board ....AL-19
    Board from England .....AL-04

  8. Re: Fanuc digital spindle drive lies about AL-04 error

    Cody, the AL-04 board had all the fuses missing and the NVRAM chip...the two EPROMs and the a/d were in place.
