A hydraulic arrangement includes a hydraulic cylinder and a hydraulic pump for its pressure medium supply, which can be driven by an electric motor of the arrangement and can be fluidically connected to a cylinder chamber via a pressure medium flow path. At least one shutoff valve is provided in the pressure medium flow path, through which the pressure medium flow path can be hydraulically disconnected for load holding of the hydraulic cylinder without drive. An operating variable of the electric motor is determined or detected upon hydraulic disconnection of the pressure medium flow path, and the detected or determined operating variable is set and tracked on the electric motor upon setting a condition at which the pressure medium flow path is opened.
A hydraulic arrangement, comprising:
A method for controlling a hydraulic arrangement having a load-holding function with at least one hydraulic cylinder and a hydraulic pump, the method comprising:
