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

Hi Sven,

For that sort of precision you probably need a flux vector drive. Flux
vector drives are VFDs that are optimised for positioning. I don't know
of any that can take step/direction so you would also need a step/dir to
+/-10V converter such as the Rutex R991H. Some VFDs are capable of flux
vector operation but make sure they can handle a +/-10V control voltage
(+10V = full forwards, -10V = full reverse). If you intend to automate
the machine you will need this setup on all axes.
