Abstract
A method and an arrangement for performing the method for the error-free conversion of the counting values of a segment counter including Wiegand sensors and the position values of a fine position sensor into a total position value using the last magnetization direction of the Wiegand wire of a segment counter as part of the information for an absolute synchronization of counting and position values.

A method for synchronizing an absolute segment counter having at least one pulse wire (Wiegand wire) sensor with an absolute fine position sensor for detecting translational and/or rotational movements of a body by converting the counting value of the segment counter and the position value of the fine position sensor into a total position value under all circumstances, wherein the information required for synchronization is obtained from the last magnetization direction of said at least one pulse wire, the information on the last determined segment from memory and the information of the fine position sensor on the current≦half segment.
An arrangement for synchronizing an absolute segment counter having at least one pulse wire (Wiegand wire) sensor with an absolute fine position sensor for detecting translational and/or rotational movements of a body by converting the counting value of the segment counter and the position value of the fine position sensor into a total position value under all circumstances, comprising:
- a segment counter having at least one pulse wire sensor;
- a position sensor for the fine resolution of the segments;
- evaluation electronics for supplying current, detecting pulses and determining the total position value.
