Usage of warning sheets in maintenance
Before performing maintenance, affix the included warning sheets (see below) to prominent positions,
such as the operating panel or the vicinity of it, for safety.
During the maintenance by two or more persons in particular, as well as using these warning sheets to
ensure safety, be sure to send signals.
This warning sheet uses a magnet. Do not use it or store it near magnetic media or any other items
susceptible to magnetic influence.

The motor that does not stop if an emergency stop button is pressed
Even if an emergency stop button is pressed, the motor for the vacuum pump does not stop. This is
because the motor prevents picked-up components from dropping. Since it is installed inside the frame,
there is no danger that workers may receive an electric shock or become entangled with it.

Handling of linear motors
CM602-L 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 power supply is in the OFF (O) 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.
