Abstract
A method for operating a position measuring system and a suitable position measuring system in which after the onset of measurement incremental signals relating to the relative position of two parts movable relative to one another are generated by the position measuring system and transmitted to an evaluation unit in serial form at predetermined sampling times. Beyond a known, defined absolute position of the two parts movable relative to one another, absolute position signals are transmitted in serial form to the evaluation unit at the predetermined sampling times. It is also possible to ascertain a differential position value from the position data, which indicates the difference, occurring in the preceding sampling interval, between the most recently determined relative position value and the first absolute position value.
