NOTE
1 When G50 X_Z_T_ ; is specified, the tool is not
moved.
The coordinate system in which the coordinate
value of the tool position is (X,Z) is set. The tool
position is obtained by subtracting the offset value
corresponding to the tool offset number specified in
the T code.
2 The G codes in the 00 group other than G50 must
not be specified in the same block as that
containing a T code.
- Compensation with coordinate shift
The work coordinate system is shifted by the X, Y, and Z tool offset
amounts. Namely, the offset amount corresponding to the number
designated with the T code is added to or subtracted from the
absolute coordinates.
Programmed path after work
coordinate system shift
The movement to this point is
by an absolute command.

Offset operation with coordinate shift
- Starting and canceling offset by specifying a T code
Specifying an tool offset number with a T code means to select the
tool offset value corresponding to it and to start offset. Specifying 0
as a tool offset number means to cancel offset.
For offset with tool movement, whether to start or cancel the offset
can be specified with parameter LWN (No. 5002#6). For
compensation with coordinate shift, the offset is started and canceled
when a T code is specified. For the cancellation of geometry
compensation, its operation can be selected with LGC (No. 5002#5).

(Note that geometry compensation can be canceled only
if LGC (No. 5002#5) = 1.)
