Arrangement and method for the automatic correction of error-containing scanning signals of incremental position-measuring devices
 An arrangement as well as a method for the automatic correction of error-containing scanning signals, which contain defined deviations from the ideal signal shape, of incremental position measuring devices is disclosed, wherein an ideal signal shape is presupposed by a downstream arranged evaluation unit. In this case the scanning signals are supplied to a processor unit, and correcting values are determined by means of a correction algorithm which are converted in turn into appropriate control signals. The analog scanning signals as well as the control signals are supplied to a correction unit, which contains several adjustment possibilities for correcting the error-containing scanning signals by the control signals acting on them. The processor unit as well as the correction unit are arranged in such a way that scanning signals, which have already passed through the correction unit, are present at the input side of the processor unit.
