Setting Setting method
Dimension word Among dimension words X, Y, Z, and A, only X, Y, and Z are supported as standard.
A is supported when the rotary axis unit is attached.
Data setting
(G10)
The ranges for parameter G10 are as follows.
Parameter: number
Function: Correction number
Acceptable range: 1 to 12
Valid range: 1 to 12
Parameter: radius
Function: Tool diameter correction
values
Acceptable range: Range 1
Valid range: 0 to 10 mm (0 to 0.3937 in.)
Tool diameter cor-
rection
(G41 and G42)
The ranges for parameters G41 and G42 are as follows.
Parameter: number
Function: Correction number
Acceptable range: 0 to 12
Valid range: 0 to 12
Spindle speed (S) The ranges for parameter S when a standard spindle is attached are as follows.
Parameter: revolution speed
Function: Spindle speed
Acceptable range: Range 2
Valid range: 4500 to 15000 (rpm specication)
73 to 84 (numeric code specication)
Feeding speed (F) The ranges for parameter F are as follows.
Parameter: feed rate
Function: Feeding speed
Acceptable range: Range 1
Valid range:
X and Y axes:7 to 3600 mm/min (0.3 to 141.7 in./min)
Z axis: 7 to 3000 mm/min (0.3 to 118.1 in./min)
The feeding speed of the A axis depends on the specications of the attached rotary
axis unit. For details, see the user's manual of the rotary axis unit.
Interpretations When NC Codes Are Omitted
This machine interprets omitted NC codes as shown below. The ability to interpret omitted NC codes is a characteristic of
this machine. If your goal is to create general-purpose programs, you should not omit codes recklessly.

Setting Setting method
Unit setting
(G20 and G21)
If these codes are not written, input will be interpreted as always being in millimeters
(G21).
Tool diameter correc-
tion
(G41 and G42)
If these codes are not written, the correction value set in the "Tool-diameter oset"
dialog box in VPanel will be used.
Workpiece coordinate
system
(G54 to G59)
If these codes are not written, the workpiece coordinate system will always be interpreted
as being workpiece coordinate system 1 (G54).
Dimension
(G90 and G91)
If these codes are not written, values will always be interpreted as being absolute
values (G90).
Feeding speed (F) If F is not written, the feeding speed will be 120 mm/min (4.72 in./min).
Spindle speed (S) If S is not written, the rotation speed displayed on the built-in panel will be used.
