SI0802008E-000= YG series: Replacement procedure for ball screws of each axis
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.

5.5.2. Adjust the axis position to the reference coordinate after replacing the ball screw
1. Click on the [Unit] button on the “Setup” screen, and then click on the [Axis] button.
2. Select the “XY” tab.
3. Input the reference coordinates before the replacement of the ball screw.
Click on the [PTP] buttons of X-axis and Y-axis and input the reference coordinates recorded in
“5.5.1. Set the reference coordinate before replacement of the Axis”, in order to move the axes.
Note:
If the position of the axes can be adjusted to the same coordinates of the X-axis and Y-axis before
replacement of the parts, it indicates that the replacement was performed successfully.

Caution:
As the coordinate affects the mounting accuracy, please adjust the position accurately.

5.6. Adjustment of the soft limit
The soft limit is the safe distance that is set in order to avoid collision of the parts during operation.
Setting the soft limit is considered to be important, as the axes require the maximum space to travel in
the machine, however on the other hand, they require the safe distance to avoid collision
.
Please do not change the setting value of the each axis.
* The soft limit value may vary depends on the model.
