Abstract
In a robot including a motor and an encoder for detecting the rotational position of the motor, the controller outputs a speed command indicating the rotational position of the motor and sends commanded-position information indicating the rotational position of the motor according to the speed command to a safety unit for detecting a fault in the encoder. When the controller is holding modified point-of-origin information of the motor and the safety unit is holding the original point-of-origin information, the controller sends commanded-position information generated based on the original point-of-origin information to the safety unit.
