ABSTRACT:
An absolute measuring system for the determination of angles or paths is described. During normal operation the encoder of this system is fed by a voltage supply (mains). If the voltage supply fails the encoder is switched to an auxiliary power supply which uses less energy. In this operating mode the encoder only calculates a coarse value of the measured value which it stores in the memory. To maintain the auxiliary power supply a chargeable memory is provided which is assigned to the encoder.
