Abstract
In automated press systems it is desirable to be able to control the actuators of an automation system associated with the press based on the speed of the press. To accomplish this, a circuit arrangement is provided which includes a pulse generator for producing a coded signal indicating the position of the press based on a press speed signal. An evaluation circuit having a parallel arrangement of a converter and a process control circuit receives these coded position signals. The outputs of the converter and process control circuit control the actuators of the automation system through pulse converters and positioning control circuits (e.g. speed and position control loops). Information as to the number of press strokes is also provided to the pulse converters through a generator. The converter can be an electronic curve shaper which controls the actuators when the press ram is moving, while the process control circuit can be a CNC control circuit which controls the actuators when the press ram is stopped.
