Abstract
The present invention is directed to a method for determining actual states of a number of adjusting elements. A position of an additional member relative to a basic member can be set by means of a number of adjusting elements. In order to determine the actual states of the adjusting elements, the additional member is firstly fixed mechanically relative to the basic member in such a way that it has only one degree of freedom. It is then possible to describe the position of the additional member relative to the basic member by means of a single scalar variable. The position of the additional member is then changed. Changes in state effected by the change in position of the additional member are detected, and the actual states of the adjusting elements are determined therefrom.

A method for determining actual states of a plurality of adjusting elements for setting a position of an additional member relative to a basic member, the method comprising the steps of:
- mechanically fixing the additional member relative to the basic member in such a way that the additional member comprises a single degree of freedom such that the position of the additional member relative to the basic member can be described by means of a single scalar variable;
- changing the position of the additional member after mechanically fixing the additional member, and detecting changes in state associated with the plurality of adjusting elements, the detected changes in state detected by sensors;
- determining the actual states of the plurality of adjusting elements based on the detected changes in state associated with the plurality of adjusting elements;
- and
- storing the determined actual states in a memory for adjusting the additional member.
