2. Activate an offset number as follows:
Press This softkey: To activate:
the {TOOL GEOMET} a tool geometry offset number
the {TOOL WEAR} tool wear offset number
The tool offset table is displayed. Currently active offset values
(if any) are indicated with an * to the right of the offset number.
3. Move the cursor on the offset table until the desired offset is shown in
reverse video. Only one geometry offset and one wear offset number
may be active at the same time.
4. Press the {ACTIVE OFFSET} softkey when the desired offset is
selected. The tool offsets are made active as described in
chapter 20.

OFFSET
There are two types of data in the work coordinate system table. They are:
the initial work coordinate system zero point locations that are called
when programming G54 - G59.3.
the external offset which is used to offset all of the G54 - G59.3 zero
points to make the same set of work coordinate systems fit a variety of
applications.
Zero Point Parameters
The zero point parameters refer to the zero point locations of all of the
work coordinate systems called out by G54 - G59.3. Enter positions for
these zero points as machine coordinate values. The control uses the
specified machine coordinate position as the work coordinate system zero
point. Refer to chapter 11 for details on work coordinate system.
Enter a machine coordinate system position for each axis of the work
coordinate system below the corresponding G-code (G54-G59.3) as
described on page 3-16.
