Abstract
A motor control for a stepping motor having windings energizable in a predetermined sequence to produce an incremental movement for each command pulse has a programmed read only memory. The control can be set so that each input pulse can command either a half or a full step and the control can further be set to have half step high speeds energize the motor for full steps for every other command pulse to thereby increase the high speed half stepping torque.
