Abstract
The encoder includes a plurality of position-detection-signal generation systems that generates electrical signals as position detection signals having different cycles, respectively; a first computing unit that calculates first position data based on the position detection signals generated by the position-detection-signal generation systems; a second computing unit that calculates second position data based on electrical signals generated by fewer ones of the position-detection-signal generation systems than in the first computing unit; and a failure determination unit that determines whether the encoder is defective based on a comparison between the first position data and the second position data.
