Abstract

In a method for the adaptive automatic control of position-adjustable drives, optimized parameters are determined from the drive motion, wherein the optimized parameters are stored with corrected parameters entered into data memory storage. In order to avoid in a method of this kind, involving a reduction of the cycle times, an overshooting in the target position, even in case of non-cyclical positioning sequences, a drive distance, determinant for an operational course, is determined between its stop points and is subdivided into calculated, consecutively numbered distance zones or angle zones and these numbers of system zones or numbers of angle zones are stored in a data memory storage. With the aid of the thus determined distance zones or angle zones, the values describing the drive motions are determined and are sub-divided in each case into a consecutively numbered zone system and are stored in a data memory storage. A data address is calculated from the number of a zone of a first zone system and from the number of a zone of at least a second zone system. An automatic control parameter field for the drive motion, stored in a data memory storage, is addressed with the calcula…
