SI0802008E-000= YG series: Replacement procedure for ball screws of each axis
51/65
5.4.2. Adjust the machine reference
1. Release the [Emergency Stop] button.
2. Click on the [Utilities] button on the “Setup” screen to activate “Calib Sm”.
3. Click on the [Axis] button on the Main menu screen.
4. Click on the [Originize] button on the “Axis” screen.
5. The data of the machine reference for each axis are displayed in the “Reference” column after the
Return-to-origin operation. Please check the data.
Figure 74
6. Loosen the coupling and adjust the axis position to the reference coordinate position.
Note:
Please adjust the position within the machine reference standard value: 50+-10% (45-55).
How to adjust the X-axis (YG100 model)
Caution:
When loosening the coupling of the motor, please loosen the one on the ball screw side.

5.4.3. Check and adjust the Y2-axis dual offset
Please make sure to check the offset balance between the Y1 motor and the Y2 motor as it may be
disrupted due to the replacement of the Y-axis motor.
1. Select “Dual drive offset” from the “Adjust Item” and click on the [Originize] button.
2. Check the value of the Y2-axis dual offset.
The standard value of “Dual Offset”: 63700 – 64300
Please repeat the procedure 1) through 3) until the value falls within the specification.
Figure 76
Note:
If the value does not fall within the specification (63700-64300) of the Dual Offset, please click on the
“No” button without saving the data. If the data is saved accidentally, please click on the [UnOriginize]
button.
3. Adjust the Dual Offset of the Y2-axis.
Loosen the two fixing bolts on the ball screw side with a hex wrench (Size 4), and rotate the ball
screw little by little in order to adjust the position to the specified value while securing the coupling.

53/65
Note:
If the value is smaller than the specification, rotate the ball screw to the anticlockwise direction. If it is
larger than the specification, rotate it to the clockwise direction.
4. Check the machine reference and the value of dual offset.
Please check if the machine reference and the value of the dual offset have not changed.
(If the variation is about 1-2 %, it is acceptable.)
5. Reconfirm the reference coordinate.
Please check if the reference coordinate has not changed.
5.5. How to set the reference coordinate
5.5.1. Set the reference coordinate before replacement of the Axis
1. Click on the [Unit] button on the “Setup” screen, and then click on the [Axis] button.
2. Select the “XY” tab.
3. Record (note down) the reference coordinate.
Adjust the cursor to the corner of the board guide that is the same height as the measuring section
of the board surface height on the reference conveyor, and then record (note down) the
coordinate.
Figure 78
Note:
As the coordinate affects the mounting accuracy, please adjust the position accurately.
