Abstract
A method for adjusting and adapting an operating point of a hydraulic actuator arrangement, in which a volume flow source is connected to a hydraulic cylinder via a pressure line that is filled with a hydraulic fluid. The method includes regulating a volume of the hydraulic fluid by the volume flow source, wherein an operating point of a position of the actuator arrangement corresponds, with respect to a predefined parameter, to a device which is to be actuated by the actuator arrangement. A modified volume of the hydraulic fluid which is necessary to adjust the operating point is derived from a rotational position of a volume flow source motor and/or of the volume flow source.

A method for adjusting and adapting an operating point of a hydraulic actuator arrangement, in which a volume flow source is connected to a hydraulic cylinder via a pressure line which is filled with a hydraulic fluid, the method comprising:
- regulating a volume of the hydraulic fluid by the volume flow source, wherein an operating point of a position of the actuator arrangement corresponds, with respect to a predefined parameter, to a device which is to be actuated by the actuator arrangement, and wherein a modified volume of the hydraulic fluid which is necessary to adjust the operating point is derived from a rotational position of the volume flow source.
A method for adjusting and adapting an operating point of a hydraulic actuator arrangement, in which a volume flow source is driven by a volume flow source motor and is connected to a hydraulic cylinder via a pressure line which is filled with a hydraulic fluid, the method comprising:
- regulating a volume of the hydraulic fluid by the volume flow source, wherein an operating point of a position of the actuator arrangement corresponds, with respect to a predefined parameter, to a device which is to be actuated by the actuator arrangement, and wherein a modified volume of the hydraulic fluid which is necessary to adjust the operating point is derived from a rotational position of the volume flow source motor.
