Abstract

In the method for adjusting a controlling element, a marking point which can be recognized by the controller unit which controls the controlling element and is at a given distance from the adjustment point is selected in the vicinity of the desired adjustment point, said distance corresponding to a given number of control pulses which are necessary in order to adjust the controlling element with close tolerances to the desired adjustment point. When a switch is used as the marking point, the distance should be so great that after movement beyond this marking point the switch passes into a precisely defined switch condition.
