I did not mean to imply that you can use the VFD to supply the 3 phase power
for anything but the spindle motor. In the context of the type of machine
the poster was mentioning a 3 phase version would be spindle only not
everything else as in an industrial 3 phase CNC machine.

I haven't ever seen one of these and likely would not like the price tag on
it.
