ABSTRACT:
A plurality of stepper motors are energized one at a time in any order by repeating sets of drive pulses generated by a single motor controller. The actual winding state of each motor is stored in a memory unit. Upon selecting the next motor the controller is cycled until the actual motor winding state and controller winding state compare. The selected motor is then switched and moved by steps to a commanded position while entering new motor winding state data into the memory unit.
