Abstract: A measurement system that includes an industrial machine and an interferometer can detect when abnormality has occurred in measurement targeted at a reflector attached to a movable body, for example, in a case where the movable body has moved too close to the interferometer. A judging section of the interferometer judges that there is abnormality in measurement targeted at the reflector on the basis of a received-light signal. Upon such an abnormality judgment, a stop command outputting section of the interferometer outputs a stop command to the industrial machine. A stopping section of the industrial machine stops the driving operation of a moving mechanism upon receiving an input of the stop command, thereby stopping the movement of the movable body. The measurement system makes it possible to prevent the industrial machine, which includes the movable body and the moving mechanism, from colliding with the interferometer.

An axis of the machine is designed to stop at a predetermined position upon the occurrence of an emergency stop. To achieve this stop position, an amount of retraction is set up to a position where a tool of machine does not interfere with a work piece or other obstacles.
