3. Move the cursor to the offset data to be modified. Use the up, down,
left, or right cursor keys to move the block cursor to the offset data on
the current page. Press the
{MORE OFFSET} softkey to change pages.
The selected item will be shown in reversed video.
Important: To modify the active work coordinate system, the control
must be in ESTOP, or CYCLE-STOP and END OF BLOCK. If it is not,
the control, along with generating the error message “ACTIVE OFFSET
CAN NOT CHANGE”, will not update the work coordinate table.
4. Units selection {INCH/METRIC}
To select units of “mm” or “inch”, press the {INCH/METRIC} softkey.

When the units are altered, all data previously entered for a particular
coordinate system or offset is converted to the newly selected units
(Inch or Metric). The current units are displayed to the right of the
work coordinate system or the offset that is being changed.
