ABSTRACT:
A stepper motor that turns a lead screw runs in microstepping mode. To compensate for positional error in microstepping, the method utilizes the characteristic sinusoidal positional error behavior that is measured at four times the frequency of the composite microstepping current waveform, using a correction factor that is in phase with this positional error.
