When this sensor is turned OFF (light emitted and not

received) while the X/Y beam is moving, the following

measures are taken.

• The excitations of the beam X/Y axis and the nozzle

U/D axis are shut off.

(At the same time, the nozzle U/D axis is braked.)

When one of the left sensors is turned off (E/NR) while

the X/Y beam is moving, the following measures are

taken. (E/NR: Light Emitted and Not Received)

• The excitation of the nozzle U/D axis is shut off.

(At the same time, the nozzle U/D axis is braked.)
