Hi Paul,
I am looking for analog motion, as in +-10v analog to the servo drives, not analog I/O for feedrate override and such. If that I not available, then I would have to start from scratch on 2 of my machines, which at this point is a non-starter. I do realize that +- 10 volts is old school, but there are still a lot of drives out there that work and use this interface.
Thanks again.
