Abstract: 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.

Abstract: A hydraulic control block for controlling a supply of pressurizing medium to an electrohydraulic or servo hydraulic axle includes a plurality of internally situated hydraulic interfaces configured to fluidically connect at least one of a source of pressurizing medium and a pressurizing medium sink of the axle to any hydraulic cylinder selected from a group of hydraulic cylinders of different structural forms, wherein the internally situated hydraulic interfaces are configured to selectively supply pressurizing medium to the selected hydraulic cylinder. The control block further includes an insert part configured as a function of the structural form of the selected hydraulic cylinder such that each of the plurality of internally situated hydraulic interfaces is one of tapped and blocked for the purpose of the fluidic connection.

Abstract: The disclosure relates to a hydraulic control block for controlling a pressure medium supply of a hydraulic cylinder of a hydraulic spindle. The hydraulic control block includes a generic hydraulic switching structure electively configurable in each of a plurality of specific hydraulic switching structures, each of the plurality of specific hydraulic switching structures having a respective hydraulic cylinder with a number of piston areas which differs from a number of piston areas in the respective hydraulic cylinders of each of the other of the plurality of specific hydraulic switching structures.
