1. A numerical control section in a control system for a machine tool or a robot that has a plurality of drive systems comprising:
- a part program; and
a drive-control unit comprising;
a plurality of control loops for closed-loop control of the drive systems of the machine tool or robot, each control loop receiving actual value signals and producing desired-value signals, and a plurality of digital-to-analog converters converting desired value signals from digital to analog values, wherein at least one of said plurality of control loops processes at least one specifiable desired-value signal as a control signal to an additional device to be controlled wherein inputs for the actual-value signals of said at least one control loop used for processing at least one control signal are set to a constant specified value.

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.
