摘要： 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.

摘要： An encoder includes a disc and a sensor. The disc has a circular surface with a central axis and is rotatable around the central axis. The disc has a slit row provided on the circular surface. The slit row includes slits arranged in a circumferential direction of the circular surface around the central axis and in a radial direction of the circular surface. The sensor is provided opposite to the slit row on circular surface. The sensor has a first light receiver and a second light receiver. The first light receiver is configured to output a first light receiving signal as the slit row rotates along the circumferential direction when the disc rotates around the central axis. The second light receiver is configured to output a second light receiving signal as the slit row moves along the radial direction when the disc rotates around the central axis.
