RE: [CAD_CAM_EDM_DRO] VEXTA 5-phase stepper motor PK566-A-A25 & Driver DFU1514

Hi Weedy,

Let me look some more. They probably use the same stepper, the number
sounds familiar!

Yes, mine is a 100V unit, probably made for sale in Japan. It runs, I just
put a 12V XFMR secondary in series (buck) with its input.

Sounds like you have optos for inputs, what with the +- signals. Look
inside, if you can, I suspect there is a switch for step/dir (I don't have
it).

The CW and CCW are a pain. One can either use some logic to change to
step/dir, or change the code in the controller program (which I did)!
