A method for calibrating a control valve with zero section - piston for a machine with a hydraulic drive, in particular for manipulators

摘要

The method for calibrating of control valves with zero section - piston for hydraulic machines drives is characterized in that, in which, during the operation of the machine automatically calibrating operation taking place with an offset value of the manipulated variable of the control equipment or control of the actuator is added together and of the permanently offset value present in certain time intervals, for example during the stoppage times of the hydraulic drive, or checked automatically by means of an algorithm is corrected.
