Abstract:
1. A control method for an axis arrangement, wherein the axis arrangement has a number of auxiliary position-controlled axes controlled in a control cycle, comprising: determining in each control cycle a specific initial set position value for each auxiliary axis based on a position value or a temporal derivation of the position value of a control axis not integrated in the axis arrangement, wherein a plurality of auxiliary axes are subordinated to the control axis; detecting in each control cycle a specific actual position value for each auxiliary axis; determining in each control cycle a specific tracking error based on the specific actual position value and the specific initial set position value of the specific auxiliary axis; determining in each control cycle a deviation value valid for all the auxiliary axes, based on the tracking errors of the auxiliary axes; and determining in each control cycle a final set position value for each auxiliary axis, based on the deviation value and the specific initial set position value of the auxiliary axis, wherein the auxiliary axis are position controlled based on the final set position value.
