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 method
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.
The ranges for parameter G10 are as follows.
Parameter: number
Function: Correction number
Acceptable range: 1 to 12
Valid range: 1 to 12
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
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 specification)
73 to 84 (numeric code specification)
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 specifications of the attached rotary
axis unit. For details, see the user's manual of the rotary axis unit.
Setting method
If these codes are not written, input will be interpreted as always being in millimeters
(G21).
If these codes are not written, the correction value set in the "Tool-diameter offset"
dialog box in VPanel will be used.
If these codes are not written, the workpiece coordinate system will always be interpreted
as being workpiece coordinate system 1 (G54).
If these codes are not written, values will always be interpreted as being absolute
values (G90).
If F is not written, the feeding speed will be 120 mm/min (4.72 in./min).
If S is not written, the rotation speed displayed on the built-in panel will be used.
