The uninterrupted power connectors and the motor that does not
stop if an emergency stop switch is pressed
Even if an emergency stop switch is pressed, the motor for the vacuum pump does not stop. This is
because the motor prevents picked-up components from dropping.
The following power connectors are uninterrupted.
1. Power connector for the CPU box
2. Power connector for the tray
3. Power connector for the inspection truck
The other motors (see below) stop if an emergency stop switch is pressed.
1. X-axis/Y-axis motor
2. Head Z-axis/
θ
-axis motor
3. Conveyor motor
4. Width-adjustment motor
5. Support vertical-axis motor

Handling of linear motors
NPM uses linear motors for driving along its X- and Y-axes.
Since extremely powerful permanent magnets are used in the linear motors, wrong handling can be
extremely dangerous even if the main power supply is in the OFF state.
In working inside the safety covers (e.g. in maintenance), follow the rules below.
1. Those who wear pacemakers must not work inside the safety covers.
2. In working, do not wear any metals such as watches, pierced earrings, and
necklaces.
3. Since the movers of linear motors become hot (80
°
C under 25
°
C environment,
90
°
C under 35
°
C environment), take care not to suffer burns.
After shutdown, it may be three hours or more before they reach room temperature.
4. Keep magnetic bodies such as iron (e.g. tools, jigs, and bolts) 40 mm away from
the linear motors.
Depending on the shapes of magnetic bodies, they may not be able to be detached from each
other.
Such as small chip components can be removed by hand.
(There is no problem if you touch the permanent magnets with bare hands.)
5. Keep watches, cellular phones, and magnetic cards 40 mm away from the linear
motors.
These devices may become broken.
As for magnetic cards, data may become corrupted.
6. Do not disassemble the linear motors.
Since the attractive power of the stators (the magnets) is extremely powerful, disassembling
them can be extremely dangerous.

Handling of the line camera
Since the line camera complies with the Class 1 limits of IEC60825-1 (Laser Safety Standards), it is
basically safe under a normal usage pattern. In maintenance or operation, however, avoid looking
directly at it.
Line camera
The two cameras are installed in the front and rear of the machine respectively.
The maximum output of the LED components used in this machine is 15 mW.
The line camera has such
a structure as will not expose workers directly to the LED radiation if they open its cover. For safety’s
sake, however, never open the cover of the line camera.
