ABSTRACT:
A method and system for controlling a digital motor to allow operation in a microstepping mode at low velocities where microstepping is advantageous and to allow operation in a non-microstepping mode at high motor velocities to take advantage of the higher torque attainable. The transition from microstepping to non-microstepping or from non-microstepping to microstepping is accomplished free of velocity perturbations in the motor phases.
