1. A movement apparatus for industrial automation, comprising:
a fluidic actuator to which a pressurised fluid can be applied, the fluidic actuator having an actuator element, and
a pressurised fluid provision device which is designed to apply the pressurised fluid to the fluidic actuator according to a control signal, in order to move the actuator element into a predefined position,
wherein the pressurised fluid provision device is designed to, whilst the actuator element is in movement towards the predefined position, successively change a pressure of the pressurised fluid according to a predefined pressure value course and to successively change a throttle opening which is used for providing the pressurised fluid according to a predefined throttle opening value course, and
wherein the fluidic actuator comprises two pressure chambers and the pressurised fluid provision device comprises a first pressure outlet for pressurizing a first pressure chamber of the two pressure chambers and a second pressure outlet for pressurizing a second pressure chamber of the two pressure chambers, and
wherein the pressurised fluid provision device is designed to change the pressure of the pressurised fluid according to the predefined pressure value course via the first pressure outlet and to change the throttle opening according to the predefined throttle opening value course via the second pressure outlet, and
wherein the predefined pressure value course is different from the predefined throttle opening value course.
 
17. A method for the operation of a fluidic actuator to which a pressurised fluid can be applied and which has an actuator element, the method comprising:
according to a control signal, applying the pressurised fluid to the fluidic actuator, in order to move the actuator element into a predefined position,
wherein the pressurised fluid provision device is designed to, whilst the actuator element is in movement towards the predefined position, successively change a pressure of the pressurised fluid according to a predefined pressure value course and to successively change a throttle opening which is used for providing the pressurised fluid according to a predefined throttle opening value course, and
wherein the fluidic actuator comprises two pressure chambers and the pressurised fluid provision device comprises a first pressure outlet for pressurizing a first pressure chamber of the two pressure chambers and a second pressure outlet for pressurizing a second pressure chamber of the two pressure chambers, and
wherein the pressurised fluid provision device is designed to change the pressure of the pressurised fluid according to the predefined pressure value course via the first pressure outlet and to change the throttle opening according to the predefined throttle opening value course via the second pressure outlet, and
wherein the predefined pressure value course is different from the predefined throttle opening value course.
