Differences between origin set and origin cancel
Function The coordinate system is shifted so the current
position becomes the designated position of the
workpiece coordinate system.
This is equivalent to "G92 X0".
(When X is the target axis.)
Changes in the The relative position counter and workpiece coor-
counter value dinate counters become "0".
Offset The G92 shift amount is updated.
Operation method (Setting the origin)
(1) Press the main menu [G92 set].
(2) Using the [↑], [↓], or the axis name address key, move
the cursor to the axis to be set.
(3) Input 0, and then press the [INPUT] key.
If the [INPUT] key is pressed without inputting a val-
ue, zero (0) will be set. (Origin zero)
(4) Repeat step (3) for each axis.
For axes that are not to be operated, press the [↓] key
and move the cursor.
Note
(1) An error will occur if a value other than 0 is set.
IB-1501453-C
Origin set
The relative position counter opens as a pop-up window.
The menu [Origin set] is highlighted.
The cursor appears at the 1st axis of the relative position
counter.
The cursor moves.
<Note>
"0.000" appears at the cursor position.
The cursor moves to the next axis.
The pop-up window closes when the origin has been set
for the last axis.

Origin cancel
The coordinate system is shifted so the zero point
of the workpiece coordinate system matches the
zero point of the basic machine coordinate sys-
tem.
This is equivalent to "G92 G53 X0".
(When X is the target axis.)
The relative position counter matches the ma-
chine coordinate counter.
The G92 shift amount and the G52 shift amount
for the G54 to G59 coordinate system becomes
"0".
If two axes or more of the same name exist such as
mixed control (cross axis control), the cursor moves
to the axis corresponding to the address key to the
axis name input first.
