ABSTRACT:
A theoretically optimum motor drive time period or drive pulse width is computed as a function of the number of steps from the present motor shaft step to the desired command step. A compensation time period is computed as a function of a previous motor drive time period and combined with the computed drive time period to produce a present drive time period for energization of the motor (12) for movement of the motor shaft (14) from the present step to the next step.
