other than the inclusion of an encoder. 6. High-level system diagram. But the internal control scheme used with closed loop stepper looks quite different than a traditional step motor control scheme.

closed loop stepper systems. Consider a side-by-side comparison of a traditional, open loop step motor system and a fully closed loop system with incremental encoder and servo control firmware ...
