The Shift (W-CS) option in the Global Program Settings function
takes effect on an axis-by-axis basis. The value is added to the shift
that takes place before the machining plane is tilted as defined in
the NC program (e.g. Cycle 7 DATUM SHIFT).
Control display
Unlike a datum shift in the NC program, the Shift (W-CS) option
in the Global Program Settings function affects the actual
position display.
The general status display shows the following icons:
No icon is displayed for offsets defined in the NC
program!
Shift (W-CS) function active (default icon of the
Global Program Settings function)
The Shift (W-CS) values are displayed on the GS tab of the
additional status display, the values from the NC program on the
TRANS tab.
