offset data on the current page. Press the

{MORE OFFSET}

softkey to

change pages. The selected item appears in reverse video.

Select data entry type:

Unit selection {INCH/METRIC}

To select units of “mm” or “inch” for the offset data, press the

{INCH/METRIC}

softkey. The units used for the currently selected

offset G-code or external offset change each time the softkey is
pressed. When the units are altered, all data previously entered is
converted to the newly selected units for that offset number.

Diameter or Radius {RADI/DIAM}

If the offset value being changed has been selected in AMP as the
diameter axis (typically the axis perpendicular to the spindle center
line), data may be entered into the offset table as either a radius or
diameter value. The current mode for this axis is displayed with an R
for radius or a D for diameter mode next to that axes offset. Pressing
the

{RADI/ DIAM}

softkey toggles the offset between these two

modes.

This softkey does not change the current mode of control operation
(as selected with G07 or G08); it only alters how data is entered into
the table. For details, refer to chapter 13 (G07/G08).
