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.
