Abstract
A pilot control unit is for at least one valve drive of a hydraulic valve with a valve slide. The valve slide can be adjusted by the valve drive, in order to supply hydraulic lines with hydraulic fluid through the hydraulic valve. The pilot control unit is set up to supply electronics and a power end stage for actuating an electrical actuator of the valve drive with electrical energy and operating commands and there is a parametrization module in the pilot control unit for this purpose, in which operating parameters for the operation of the at least one hydraulic valve by the valve drive thereof are stored.

Pilot control unit for at least one valve drive of a hydraulic valve with a valve slide, wherein the valve slide can be adjusted by the valve drive, in order to supply hydraulic lines with hydraulic fluid through the hydraulic valve, wherein the pilot control unit is set up to supply electronics and a power end stage for actuating an electrical actuator of the valve drive with electrical energy and operating commands and thcrc is via a parametrization module in the pilot control unit, in which operating parameters for the operation of the at least one hydraulic valve by the valve drive thereof are stored.
Method for operating a valve drive for a hydraulic valve, wherein the valve drive receives operating commands from a separate pilot control unit via a bidirectional data transmission and sends actual values of the hydraulic valve back to the pilot control unit via the bidirectional data transmission, and wherein the pilot control unit contains operating parameters stored in a parametrization module for the valve drive and hydraulic valve, which are used along with the actual values and external inputs to generate the operating commands.
Computer program product having a non-transitory computer readable medium that stores commands which cause a pilot control unit for a valve drive of a hydraulic valve to perform a method for operating the valve drive, wherein the valve drive receives operating commands from the pilot control unit via a bidirectional data transmission and sends actual values of the hydraulic valve back to the pilot control unit via the bidirectional data transmission, and wherein the pilot control unit contains operating parameters stored in a parametrization module for the valve drive and hydraulic valve, which are used along with the actual values and external inputs to generate the operating commands.
