Center point relative / absolute coordinate specification (G98, G99)
As is the case with target coordinates, center point coordinates can also be specified by
selecting relative coordinates or absolute coordinates.
Center point coordinates are specified by selecting G-code G98 or G99.
G-code Function Description Remarks
G98 Absolute coordinate
specification
(center point)
Specifies the center point of circular
interpolation as absolute
coordinates
After G98 is set, absolute
coordinate specification remains
ef
fective until G99 is set.
G99 Relative coordinate
specification
(center point)
Specifies the center point of circular
interpolation as relative coordinates
(If G98 is not specified, relative
coordinate specification will be
used.)
After G99 is set, relative coordinate
specification remains ef
fective until
G98 is set

Notes on center point coordinate specification
●
For relative and absolute coordinate specifications, different G-codes are used for target
coordinates and center point coordinates.
● We recommend that relative coordinates (default setting) be used for center point
coordinates, as using relative coordinates makes input easier.

Center point relative coordinate specification (G99)
Center points can be specified as relative coordinates, as below. Coordinates other than center
point coordinates are specified as absolute coordinates.
