Abstract (en)

[origin: EP2192309A2] The method involves supplying a pressurizing medium quantity to an actuator by a variable displacement pump (13). A speed deviation is detected, where the speed deviation results from the deviation of a speed (n) of an electric motor (14) from a target value for a speed (ns). An independent claim is included for a regulating circuit for controlling pressurizing medium supply for hydraulic actuator of a cyclically working machine.
