Abstract: The absolute optical encoder was widely used in servo, robots and other high-precision control fields. With the increase of the localization rate of devices, the failure probability of products increases, which affects the reliability of the system. The summarizes and analyzes the common faults of the domestic absolute optical encoder during the use of AC servo motor and puts forward the fast location and solution of the faults of the motor. This method has accumulated the experience for the design improvement of the domestic encoder.

Key words: optical encoder, servo motor, fault
