Parameters
This command does not have any parameters to set.
Function
This command selects a plane, the reference of Circular Interpolation (G02/G03), Cutter Compensation
(G40/G41/G42), and Coordinate System Rotation (G68/G69). You can specify XY (G17), ZX (G18),
and YZ (G19). XY is specified at startup. Refer to G02, G03 Circular Interpolation on page 2-8, G40,
G41, G42 Cutter Compensation on page 2-40, G68, G69 Coordinate System Rotation on page 2-57 for
details.
Precaution for Usage
Depending on plane selection of G17/G18/G19, some G codes change operation while others do not
change operation. The following shows operations changed according to plane selection.
• G41/G42 (Cutter Compen-
sation):
• G43/G44 (Tool Offset):
• G74/84 (Fixed Cycle):
Refer to the following table for the relationship between plane selection and each G code.

The cutter radius is compensated for the selected plane. An error will occur if
planes are switched during cutter compensation.
The tool length is compensated for Z-axis regardless of the selected plane. No
error will occur even if planes are switched during tool offset.
During a fixed cycle, the cutting is executed in the Z-axis direction regardless of
the selected plane.
G41/G42 (Cutter Com-
pensation)
The cutter radius is com-
pensated for the XY
plane.
The cutter radius is com-
pensated for the ZX plane.
The cutter radius is com-
pensated for the YZ plane.
G43/G44 (Tool Offset)
The tool length is compen-
sated in the Z-axis direc-
tion.

G74/84 (Fixed Cycle)
Fixed cycle operation is
fixed to the Z-axis direc-
tion.
