1. A method for damping a movably mounted attachment part of a machine, wherein the attachment part is movable by a hydraulic cylinder, and the hydraulic cylinder is actuated via a bidirectional hydraulic pump, the method comprising:
during a measurement phase, receiving a measured value of a pressure in a load-side chamber of the hydraulic cylinder; and
during operation of the machine subsequent to the measurement phase, controlling a pressure regulator of the bidirectional hydraulic pump to the measured value as a setpoint value such that the bidirectional hydraulic pump conveys fluid into the load-side chamber and out from the load-side chamber to maintain the pressure in the load-side chamber of the hydraulic cylinder at the measured value so as to damp the movably mounted attachment part.
