Abstract

A system including a pneumatic actuator with an actuator member and a compressed air supply device which is configured to apply compressed air to the pneumatic actuator in order to set the actuator member in an actuator member movement towards an end position of the pneumatic actuator, wherein the compressed air supply device is further configured to provide an end position damping for the actuator member movement and, during the end position damping, to adjust a conductance value of a discharge valve, via which the compressed air supply device discharges compressed air from a pressure chamber of the pneumatic actuator which pressure chamber counteracts the actuator member movement, in accordance with a conductance characteristic in dependence of a driving force acting on the actuator member.
