This is one of the places where the 3 phase stepper/servo really shines.
2 reasons:
1.wire hem up so if they loose a step, the alarm stops linuxcnc it it
track useing the alm signal as an e-stop input.
2. the error determines the motor current. So if its working easy,
little warming, and your power meter doesn't spin as fast. But that also
means if the error starts to rise, the current to the motor can be
increased to whatever amps it takes to restore the low error state.
I am presently using 4 of these motors and every time I replace a non
servo stepper, I've doubled the speed and acceleration that axis of the
machine can do, and I'm doing it w/o step loss. Now there are smaller
ones available in the nema-17's used on 3d printers so two of my bigger
printers are in the midst to getting these newer motors installed.

Are the machine acceleration limits as high as they can be? That
should help somewhat.
