Abstract
A control system for controlling operating steps of a press including a coded pulse generator for providing a coded pulse output in dependence upon the position of a drive shaft of a press drive and a signal generator responsive to the stroke rate of the press for providing an output signal proportional to the stroke rate of the press. A summing unit receives the coded pulse output from the coded pulse generator and the output signal of the signal generator for providing a corrected coded pulse output. A decoding unit is provided for decoding the corrected coded pulse output of the summing unit and for supplying a decoded pulse output to a pulse distributor which provides an output on at least one of a plurality of output paths in accordance with the decoded output of the decoding unit. At least one regulating member for controlling an operating step is coupled to the pulse distributor for receiving an output therefrom in accordance with the position of the drive shaft and the stroke rate of the press.
