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. Fig. 1X42 Senso…

4.2.3 X-Axis Collision Detection Sensor

This sensor is provided to detect that both heads have approached

abnormally for protection of the X/Y beam.

When this sensor is turned OFF (light emitted and not

received), the following measures are taken.

• Both heads stop rapidly.

When this sensor is turned OFF (light emitted and re-

ceived), 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.)
