What is the interface? It is very unlikely to be RS-232. Much more likely
to be an RS-422 type interface. You'll need to get the manuals on the
drives. Some of the RS-422 interfaces can be set up with the proper cable
to work from a standard PC serial port for testing and configuration. I
did this with a Yaskawa servo-pack drive. But, I don't think you can
actually
run a CNC system like that, due to the electrical noise. That's why
they use
the RS-422, to combat that noise. That requires a special interface
card for
the PC.
