The control system includes a motor driven control circuit, a process control unit coordinating with the right sequence the motor control unit successively on the input and output side to the servo system and a first computing circuit preceding the motor control circuit. A difference forming unit has input and output connected to the process control unit and has an output connected to the first computing circuit. A switching means is connected to the difference forming unit and connected to an input multiplexer of the control system. A second computing unit is connected to the motor control unit and to the switching unit.
