Motion's spindle.0.speed-out is always in RPM. Encoder outputs both 'velocity' and velocity-rpm (not sure why as scale
should get us to either unit?) so I can plug RPM into the PID (I think both the PID.command and PID.feedback should be
in the same units), but then pid.output passes through ABS - then to the frequency-input of the VFD .
The PID output should self correct (via P) for what ever unit is used to jump it up to inverter frequency - but that
might be sub optimal? Not sure this matters? Do I need to scale RPM to frequency?
I can fix the vfd component so it has a frequency scale input - is it worth it
to fix this?
