Abstract
A servo system includes a motor having a stator and a movable element which moves relative to the stator, an encoder which detects at least one of a position and a speed of the movable element of the motor, and a controller including first circuitry which controls operation of the motor based on a detection result of the encoder. The first circuitry of the controller transmits a first command signal that changes a communication speed between the encoder and the controller from a first speed to a second speed which is higher than the first speed, and the encoder includes second circuitry which changes the communication speed between the encoder and the controller to the second speed when the first command signal is received from the controller.
