5-7 NC Code Specifications
Effective range: 0 to 8
Spindle speed (S)
When the standard spindle is installed, the parameter
range for S is as follows.
Parameter: revolution speed
Function: Spindle speed
Acceptable range: Range 2
Effective range:
4500 to 15000 (Specified as rpm)
73 to 84 (Numerical-code specification)
Feed rate (F)
The parameter range for F is as follows.
Parameter: feed rate
Function: Feed rate
Acceptable range: Range 1
Effective range:
XY-axis: 7 to 3000 mm/min (0.28 to 118 inch/mm)
Z-axis: 7 to 1800 mm/min (0.28 to 70.8 inch/mm)
Note: The feed rate for the A axis is dependent on
the specifications of the rotary axis unit installed. For
more information, refer to the documentation for the
rotary axis unit.
Interpretation of Omitted NC Codes
When the format for NC codes is abbreviated and one
or more NC codes are omitted, the machine performs
interpretation as described below. The method of
interpretation is specific to the machine. When you
want to make a program generic, needless omission
should be avoided.
"NC Code Reference Manual"
Measurement unit (G20 and G21)
When these are omitted, the interpretation is always
for millimeter input (G21).
Tool-diameter offset (G41 and G42)
If these data are not written, the correction value
that was set at the [Tool-diameter Offset] dialog on
the VPanel is used.
88
Chapter 5 Appendix
Chapter 5 Appendix
Workpiece coordinate system (G54 through
G59)
When these are omitted, the interpretation is always
for workpiece coordinate system 1 (G54).
Dimension (G90 and G91)
When these are omitted, the interpretation is always
for absolute specification (G90).
Feed rate (F)
When F is not stated, the feed rate is 120 mm/min.
Spindle speed (S)
When S is not stated, the speed set at VPanel's main
window is used.
