    Abstract: Disclosed is a monitoring device for a rotary encoder electronically connectable to the monitoring device. A pulse generating unit generates a comparison pulse signal by extracting a portion corresponding to a specific phase range from a first pulse included in a first pulse signal output from the rotary encoder. The rotary encoder detects rotation of a rotating body and outputs the first pulse signal and a second pulse signal, the first pulse signal and the second pulse signal having a phase difference from each other. A determining unit determines an abnormality of the rotary encoder, based on a state of a pulse of the comparison pulse signal at a specific timing of a second pulse included in the second pulse signal.
