Abstract
An encoder which detects information on the position or the speed of a motor includes memory which stores motor-specific information on the motor to be mounted on the encoder, a mount determination unit which determines whether the encoder has been removed from the motor, and a memory information erasure unit which erases the motor-specific information stored in the memory when the mount determination unit determines that the encoder has been removed from the motor.
