I have never tried multiple motors on one VFD....and I'm not sure I'd want to!
Regardless of the nominal RPM of a motor, every motor is going to run a little bit different. Likewise, the load applied to each motor is going to vary slightly.
Invariably, production lines have some means to adjust the line between stages, to account for these factors. Yet, I still would not count on every motor running at the same speed. I'd really like there to be separate VFD's.
