Controlling a hydraulic drive for a hydraulic consumer alternately pressurized in opposite directions, the hydraulic drive comprising a hydraulic machine driven by an electric machine and featuring variable displacement adjustable through zero, wherein a rotational speed of the hydraulic machine controlled by the electric machine, includes varying displacement so that conveying direction of hydraulic fluid is alternated using a cyclically varying volumetric flow specification, to perform direction reversals. After direction reversal during a first change time period, the rotational speed is increased from a first rotational speed set at the end of the direction reversal to a second rotational speed, and within a second change time period after the first change time period, the rotational speed is decreased until the first rotational speed is reached. The displacement is varied during the change time periods depending on the rotational speed and volumetric flow specification to comply with the volumetric flow specification.
A method for controlling a hydraulic drive for a hydraulic consumer alternately pressurized in opposite directions during operation, wherein the hydraulic drive comprises a hydraulic machine which is driven by an electric machine, and includes variable displacement adjustable through zero, wherein a rotational speed of the hydraulic machine is adjustable by controlling the electric machine, comprising:
