Abstract
Embodiments are directed to a stepper motor and a controller, where the controller measures a parameter associated with a current of the stepper motor prior to support of commanding a step in connection with the stepper motor. That is, the controller commands the step in connection with the stepper motor, measures a parameter subsequent to commanding the step, compares the measurements of the parameter, and determines whether a fault exists with respect to the stepper motor based on the comparison of the measurements.
