3 In automatic reference position return (G28), the end point
(reference position) is not affected by manual handle interruption.
However, the midpoint is in the workpiece coordinate system, so
that the position shifted by the amount of interruption becomes
the midpoint.
- Cancellation of the amount of interruption
Operation by which the workpiece coordinate system shifted by
manual handle interruption from the machine coordinate system is
returned to the original workpiece coordinate system is referred to
cancellation of the amount of interruption.
When the amount of interruption is canceled, the workpiece
coordinate system is shifted by the amount of manual handle
interruption, and the amount of interruption is reflected in the absolute
coordinates.
Interruption shifts the workpiece coordinate system from the machine
coordinate system.
