Abstract: A method for controlling the drive of a hydraulic press and an associated device for carrying out the method are proposed, the piston/cylinder unit (2,3) belonging to a press ram (1) being driven via several hydraulic devices (10, 12, 20) connected in series. Depending on the operating phase of the press, the hydraulic devices are here used as required either as hydraulic motors or hydraulic pumps, which effect a delivery of a pressure medium into the respective cylinder chamber (7, 8).
