Maintenance

4. Weekly inspection

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.

Open the [Unit] – [Conveyor] tab.

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.

Maintenance

5. Monthly

5.1 Inspecting each axis

Inspect the ball screws and the guides on each axis.

Check the following points.

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.
