In a robot that operates an arm by driving a motor with a servo driver, when the load current of each of the motors exceeds the set level for a set time or more, or when the load current of each of the motors exceeds the set level. when the change in the speed command voltage to the servo driver is smaller than the set value, or when the change in the load current of each motor is more than the set value and the speed command voltage to the servo driver is smaller than the set value. or when the speed command voltage to the servo driver exceeds a set level, it is determined that there is an abnormality and outputs a stop signal to the robot control panel. .
