ABSTRACT:
In a numerical control system for controlling a machine tool or a robot, control loops that are not used for the control of drive systems of the tool or robot are utilized to actuate other digital or analog devices. The actual value inputs of these control loops are preferably set to a constant value, such as zero, so that the control loop will switch specified control data through to its output as control signals. The control signals are converted by means of digital-to-analog converters into control voltages.
