4.2.5 Excessively Inserted Nozzle Detection Sensors

These sensors are provided to protect the placement heads against

any vacuum nozzle that is excessively inserted due to an error in the

pattern program.

When one of these sensors is turned OFF (light emit-

ted and not received), 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 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.)
