Abstract
For path control of a plurality of drives, i.e. for driving a plurality of drives in different axes in geometrical path dependence, to obtain high accuracy it is necessary for the lag error of the drives to remain constant. According to the invention for this purpose a circuit arrangement is proposed in a cascade structure in which from the speed of each individual path drive and the control deviation determined from the actual value and desired value of the position a difference signal is formed which is integrated and added to the output signal of a P controller.
