Instruc
tion
Name Outline of function
00 Non-modal --- G04 Dwell Stops the CNC coordinate system for a predefined
period of time.
00 Non-modal --- G09 Exact Stop Executes a forcible control deceleration stop
together with the registration of in-position at the
termination of a block.
00 Non-modal --- G28 Return to Reference
Point Moves the tool to the reference point (position 0)
via the middle point specified by an argument of
the instruction.
00 Non-modal --- G30 Return to 2nd, 3rd or
4th Reference Point Moves the tool to the 2nd, 3rd and 4th reference
point.
00 Non-modal --- G31 Skip Function Provides Rapid Positioning (G00) and input stop.
00 Non-modal --- G52 Local Coordinate Sys-
tem Set Creates coordinates in the Work Coordinate Sys-
tem.
00 Non-modal --- G53 Dimension Shift Cancel Runs commands in the machine coordinate sys-
tem.
01 Rapid Position-
ing G01 G00 Rapid Positioning Performs a point-to-point operation in the minimum
time by following the restrictions of CNC motor set-
tings.
G01 Linear Interpolation Moves a CNC motor from the current position to a
specified position.
G02 Circular Interpolation in
CW direction Moves the tool on an arc path on the XY, YZ, or ZX
plane.
G03 Circular Interpolation in
CCW direction
02 Plane G17 G17 X-Y Plane Selection Changes a plane, the reference of Circular Interpo-
lation (G02/G03), Cutter Compensation
(G40/G41/G42), and Coordinate System Rotation
(G68/G69).
G18 Z-X Plane Selection
G19 Y-Z Plane Selection
03 Distance G90 G90 Absolute command Enables absolute position mode for all axes in the
CNC coordinate system, and moves the axes to a
specified position in the current coordinate system.
G91 Incremental command Enables relative Incremental position mode for all
axes in the CNC coordinate system, and moves
the axes a certain distance from the last command
position.
06 Unit Operation
depends on
the Orthogo-
nal Axis
Command
Unit setting G20 Inch input Switches all the settings of the CNC coordinate
system, command values, and the unit of current
values.
G21 Metric input
