Abstract
A position measuring system features a position measuring device (1), an interface to transmit the position signals of the position measuring device (1) to an electronic control unit, a microcontroller (2) and a non-volatile memory (3), in which characteristic values of the position measuring system are stored, and from which said values can be read out via the interface. During the operation of the position measuring system the microcontroller (2) records state variables of the position measuring system or of a servo drive, respectively, and stores such variables in the memory (3).
