106
In addition to G90, the absolute coordinate system is put into effect when a REF-
ERENCE ORIGIN RETURN (G26), WORKPIECE ORIGIN RETURN (G27), or
ORIGIN SEARCH (G28) function is executed.
Example Program The following example shows the different axis operations with absolute and
incremental specifications.
::
N010 G90
N011 G01 X50 Y50
N012 G01 X100 Y20
::
The axis operation would be performed on
this path with incremental specification.
5-5-30 G91: INCREMENTAL SPECIFICATION
Specifies the use of relative coordinates in axis operations.
Format G91
Parameters None
Description This function specifies that positioning axis operations are performed relative to
the current position. After this function is executed, the coordinate data in axis
movement commands is treated as the distance to be moved from the current
position.
Example Program The following example shows the different axis operations with absolute and
incremental specifications.
::
N010 G91
N011 G01 X50 Y50
N012 G01 X100 Y20
::
The axis operation would be performed
on this path with absolute specification.
