Abstract

A method serves to actively perform vibration damping of driven elements of workpiece transport devices in and on shaping machines, especially presses and punches. A measured state value of the driven element or one reconstructed by an observer is determined. The state value is then entered into a damping regulator which affects the drive of the driven elements. A damping regulating circuit is provided in addition to a position regulating circuit.
