4.1 Checking the board sensor condition
This equipment uses transmission type fiber sensors as the board sensors. Periodically check that these sensors
correctly operate even when the conveyor rail width is changed.
1
Open the [Unit] – [Conveyor] tab.
2
Press the [Width] button to change
the conveyor width.
1. When the “Conveyor” dialog box
appears, enter the maximum conveyor
width in the "Target Width" box and press
the [OK] button. The conveyor width will
automatically change to the specified
size.
2. Then, enter the minimum conveyor width
(50mm) in the “Target Width” box and
press the [OK] button. The conveyor
width will automatically change to the
specified size.

Check whether an error has
occurred.
The conveyor sensor is operating properly
unless an error message appears when the
conveyor width is changed. No further
check is necessary.
If an error message appears, follow the steps
below to adjust the sensor.

Adjusting the conveyor sensor
If an error occurred when the conveyor width was
changed, perform the auto-tuning of the conveyor
sensor.
1. Open the [Unit] – [I/O] tab.
2. In the Output list, select “CONVEYOR” (T01000E0).

NOTE
For the dual lane specifications, (T01000E0) corresponds
to lane 1 while (T01000E2) corresponds to lane 2.
3. Press the [ON/OFF] button to change to 0 (OFF)
→
1 (ON)
→
0 (OFF) and perform the auto-tuning.
4. Press the [Width] button again to change the
conveyor width in the same manner as described in
Step2. When no error message appears, the sensor
operates correctly.

5.1 Inspecting each axis
Inspect the ball screws and the guides on each axis.
Check the following points.
n
NOTE
A grease spattering prevention cover is attached along each axis. Remove the cover before inspection and reattach
it in place after inspection.
Checkpoints
1. Any foreign matter or chips adhering to the ball screws and linear guides?
2. Do the ball screws and linear guides have the correct amount of grease?
Check if grease has flowed off or splattered in the air failing to adhere. Also check if grease has discolored or
hardened.
3. Any abnormal sounds from the ball screws?
Press the emergency stop button. Then check for any abnormal sounds while pushing the unit by hand along the X-axis
or Y-axis back and forth.
Countermeasures
1. Ball screws and linear guides may be damaged when chips or debris bite into them. If chips or debris are adhering,
wipe them off along with the grease or remove with tweezers, etc.
2. Apply grease while referring to "Cleaning and greasing the ball screws and linear guides of each axis" described later.
3. Consult your YAMAHA sales office or representative when abnormal sounds occur even after trying the
countermeasures in the above steps 1 and 2.

CAUTIN
• When handling grease or lubricant, read and follow the precautions listed in section "3.2.2 Lubricating tools and
grease", in this chapter.
• If abnormal noise is emitted from the ball screw or guide of each axis, then contact our sales representative for
assistance. Disassembly and cleaning of the ball screw or guide by the user will void the warranty.
