ABSTRACT:
A motor controller system for operating a plurality of step motors. The step motors are arranged in a number of motor groups each having no more than “N” step motors. A group multiplexer will deliver feed signals to the correct numbered motor of a motor group. There is a single 1 axis motor control and an output drive for each motor number of a group. The 1 axis motor control supplies the group multiplexer with motor group data so that the group multiplexer will supply the correct motor group and the 1 axis motor control also individually enables the motors of that group which are to be operated and conjointly supplies all the output drives with a desired feed signal.
