Absolute encoder including abnormality detection unit for detecting abnormality of consumption current
An absolute encoder that receives a current from an electronic power supply includes: a plurality of regulators connected in parallel with one another that receive a drive current from an electronic power supply in which a magnitude of a constant voltage output to the absolute encoder and a magnitude of a drive current needed for outputting the constant voltage are different; a voltage detection unit configured to detect an output voltage of at least one regulator of the plurality of regulators; and an abnormality detection unit for detecting an abnormality of a current from an electronic power supply consumed when the absolute encoder is driven based on the output voltage detected by the voltage detection unit.
