Abstract
A method for operating a drive mechanism comprising bringing a mobile element into a predetermined reference position with the help of an engine and setting an absolute position signal to a reference value allocated to a reference position; changing the position of the mobile element with the help of the engine and creating an incremental position measurement signal, depending on the change in position, for the mobile element; controlling the incremental position measurement signal and following the absolute position signal when a change in the incremental position measurement signal occurs; repositioning the mobile element in the reference position with assistance of the engine and determining the position value indicated by the absolute position signal in the reference position; determining a difference value from the position value and the reference value and saving the difference value in a data storage; and, repeating steps b) through e) are performed at least once.
