07 Tool radius G40 G40 Cancels tool compen-
sation Enables selection of a tool for control, automati-
cally moves the tool to the left side or right side of
the programmed path, and correct the radius of the
tool.
G41 Tool Compensation, left
G42 Tool Compensation,
right
08 Tool length off-
set G49 G43 Tool Offset, positive Corrects the position in the Z-axis direction.
G44 Tool Offset, negative
G49 Cancels tool offset
09 Fixed cycle G80 G74 Left-handed Tapping
Cycle Performs reverse tapping machining.
G80 Fixed Cycle Cancel Cancels a fixed cycle.
G84 Tapping Cycle Performs tapping machining.
10 Return level G98 G98 Fixed Cycle Return to
Initial Level Sets the return position of a fixed cycle to the initial
level.
G99 Fixed Cycle Return to
R Point Level Sets the return position of a fixed cycle to the R
point level.
11 Scaling G50 G50 Cancel scaling Scales the current coordinate system.
G51 Scaling
14 Coordinate
System Selection No Work
Coordinate
System is
selected (all
coordinate
axis have
zero offset). G54 1st Work Coordinate
System selection Changes the current coordinate system to a speci-
fied one defined by the user by using the offsets of
X-, Y-, Z-, A-, B-, and C-axis.
G55 2nd Work Coordinate
System selection
G56 3rd Work Coordinate
System selection
G57 4th Work Coordinate

15 Path Control G64 G61 Exact Stop Mode Stops operation between blocks to prevent corner
rounding and blending from being executed.
G64 Continuous-path Mode When two or more sequential operations are
aligned, the former can be blended with the latter
and accelerated/decelerated.
16 Rotation G69 G68 Enables rotation Rotates the current coordinates.
G69 Disables rotation
22 Mirroring G50.1 G50.1 Cancel Mirroring Mirrors the current coordinates.
G51.1 Mirroring
23 Multi-block
Accelera-
tion/Deceleration
Rate G501 G500 Enables multi-block
acceleration/decelera-
tion rate Reads the path ahead, and adjusts the accelera-
tion or deceleration rate.
G501 Disables multi-block
acceleration/decelera-
tion rate
