Abstract

A servo control has an electromechanical or electrohydraulic support of setting strokes of a handle. A constantly running electric motor is coupled to a control member of the servo control by power flux which can be controlled by the handle. By way of an electronic load recognition, the load which is variable in dependence on the power flux and against which the electric motor has to operate is utilized to control the output of the electric motor. That is, the electric motor is switched to greatly increased output in the case of increased load.
