Working Paper

This paper describes a hardware system designed to facilitate position and velocity control of a group of eight stepping motors using a PDP-11. The system includes motor driver cards and other interface cards in addition to a special digital control module. The motors can be driven at speeds up to 3000 rpm. Position feedback is provided by shaft encoders, but tachometers are not used.
