Abstract
A position control system for the movable machine parts of industrial robots, machine tools and the like comprising an actual position transmitter and counter arrangement coupled to each movable machine part. The readings of the counters are transmitted to a computer control, via a serial data bus such as a lightguide bus, which then compares the readings to reference values. Positioning commands for the drives of the movable machine parts are derived from the computer control comparisons and issued to the respective drives.
