Re: [CAD_CAM_EDM_DRO] Does a VFD do the trick?

Flux vector drive, never heared consciciously that name. +...-10V I can
handle with a analogue output. I will try to get one for a test from
Telemecanique where a friend works. Z and Y are standard squirrel cage
motors
X is hydraulic with mecanical switching.
