4.4.3 Clear the Shift Amount for Coordinate System Setting When Manually Returning to the
Reference Position
When the reference position is reached by the manual reference position return, the coordinate system setting shift
amount can be cleared by setting the parameter "#1279 ext15/bit5" to "1".
After returning to the manual reference position, the hypothetical machine coordinate system which includes the
coordinate system shift amount switches to the basic machine coordinate system which does not include the coordinate
system shift amount. (Refer to the figure below.)
The local coordinate system is canceled at the same time as clearing the coordinate system setting shift amount.
This function is valid for the manual reference position return, and the coordinate system setting shift amount cannot be
cleared when the reference position is reached by the automatic reference position return.
