Abstract

Methods and systems for carrying out a displacement movement of a drive element of a pneumatic drive unit. The method including by way of a first valve unit of a valve device, carrying out a pressure closed-loop control of a first pressure chamber of the pneumatic drive unit, in order to effect the displacement movement along a displacement path, by way of a second valve unit of the valve device, providing a throttle function for compressed air which given the displacement movement escapes from the second pressure chamber of the pneumatic drive unit, in order to influence the displacement movement, and in dependence on a position of the drive element and/or the time and/or a trigger signal, adapting a pressure setpoint of the pressure closed-loop control and a throttle opening of the throttle function during the displacement movement.
