Check the grease condition.
1. After the aging operation stops, press the
emergency stop button and detach the
feeder exchange carriate, then open the
machine safety cover.
2. Wipe off grease which has piled on the
guide and the guide end face.

CAUTION
Repeat Steps 7 and 8 until grease piling no longer occur.
Beginning production with grease piling remains could
cause the grease to spatter.

Clean linear scale using a lint-free cloth
to dry-wipe.
If significant dirt exists, wipe it in one direction
with a lint-free cloth applied a few drops of
ethanol, then dry-wipe the area.

2.3 Conveyor unit
2.3.1 Check the conveyor sensor and its operation
The YRM20 is installed transmission type sensors as conveyor sensor.
The beam receiving condition of sensor varies depending the distance between the beam emitter and receiver
upon changing the conveyor width.
Upon changing the conveyor rail width, the Conveyor Sensor Tuning function is actuated to rewrite the sensor
threshold value automatically by remembering the changing receiving condition of sensor. It is required to be
checked periodically if it operates correctly.

Checking operation
1
Prepare for work by checking that there
are no board on the coneyor nor pushup
pins at the conveyor motion range.
2
Change the conveyor width.
1. Open the [Unit] - [Conveyor] screen and
press the [Width] button.
2. Conveyor width change screen appears,
then input any conveyor width and press the
[OK] button.
3
Check the message.
After changing the conveyor width, as long as
the Conveyor Sensor Tuning function actuates
normally, no error message appears.
Here finishes the operation.

When an error message appears
Perform the conveyor tuning as following procedure.
1
Press the [Conveyor Sensor Tuning]
button at the right side of the [Unit]
- [Conveyor] screen.
2
Check the sensor condition.
Change the conveyor width again, then check
if any error message appears.
The conveyor sensor tuning finishes when no
error message appears.
►
When an error message still appears
It may be the beam receiving condition deterioration around the sensor, the sensor (amplifier) breakage,
or the fiber broken.
Remove dirt and dust on the sensor unit using a lint-free cloth or a lens blower brush, then check that no
error message appears after changing the conveyor width again.
