Mark,
There is a servo enable button but it basically enables the whole
system. Not sure why anyone would want to have manual control when a CNC
mill is pretty much like a manual mill with accurate DRO's and power feeds
on all axes when in operation. I use the Cincinatti arrow 500 I have
retrofitted as a manual machine all the time LOL. Just jogging around and
whatnot and setting offsets to get dimensions on parts is a breeze. I am
not sure you would be able to control the VFD with linuxCNC disabled or
servos disabled unless you hade some other input like a potentiometer on an
analog input and setup the VFD to run outside of linuxCNC... I am sure
something would be doable that way not sure how good an idea it is..
