4.1 Lifted Feeder Detection Sensors

These sensors are used to prevent any machine operation (to protect the ma-

chine) when a tape feeder is not installed correctly.

When one of these sensors is turned off (E/NR: Light Emitted

and Not Received), the following measures are taken.

•

The power to drive both X/Y beams (Sides A beam and B

beam) is shut off.

4.2 Lifted Nozzle Detection Sensors

These sensors are used to protect the placement heads when a vacuum nozzle

is jerked out of the nozzle stocker while the X/Y beam is moving.

4.3 Beam Approach Detection Sensor

This sensor is used to detect that both X/Y beams are abnormally approaching

and protect the X/Y beam.

4.4 Stationary Position Stopper Detection Sensors

These sensors are used to check whether the stationary position stopper of the

X/Y beam has moved back during X/Y beam movement and the X/Y beam is

set ready to be moved.

taken.

•

The power to drive the pertinent up/down axis is shut

off.

4.5 Excessively Inserted Nozzle Detection Sensors

These sensors are used to protect the placement heads when a vacuum nozzle

is inserted excessively due to a mistake in the pattern program.

• “X” in ( ) represents “A” or “B” in the figure below.
