2.2.2 Symbols Addressing Numerical Values
The symbols addressing numerical values are used to read the modal data of the
current block.
2.2.2.1 Addressing a Value
[
•
Rxx] Addressing a value.
The symbol [
•
Rxx] is used to address a value corresponding to the elements specified
by xx.
[
•
RF] Feed rate
(units as programmed by G93, G94 or G95).
[
•
RS] Spindle speed
(G97: format according the spindle characteristics declared in
machine parameter P7).
[
•
RT] Tool number.
[
•
RD] Tool correction number.
[
•
RN] Number of the last sequence (block) encountered.
If the block number is not specified, the last numbered block is
analysed.
[
•
RED] Angular offset.
[
•
REC] Spindle orientation (milling).
[
•
RG4] Dwell time programmed (G04 F..).
This nonmodal function may however remain stored. Its value
can therefore be read if the system is in state G999 or G998.
[.RG80] Number of the calling function in a subroutine called by G
function.
In a subroutine called by G function, the number of the calling
function is addressed by [.RG80] (in state G80, its value is zero).
[
•
RNC] Value of NC (spline curve number).
[
•
RDX] Tool axis orientation.
Defined by the following signs and values:
+1 for G16 P+ +2 for G16 Q+ +3 for G16 R+
-1 for G16 P- -2 for G16 Q- -3 for G16 R-
[
•
RXH] Nesting level of the current subroutine.
1: main programme
2: first nesting level
3: second nesting level, etc. (8 possible nesting levels)
