Thread:
0.001 ... 2000.000
Belongs to the Z axis; otherwise,
as with I
See G2, G3 and G33,

L Subroutine; name
and call
7 decimals;
integer only, no sign
Instead of a free name, it is also
possible to select L1
...L9999999;
this also calls the subroutine
(UP) in a separate block,
Please note: L0001 is not
always equal to L1.
The name "LL6" is reserved for
the tool change subroutine.
L.... ;separate block
M Additional function 0 ... 99
only integer, no sign
For example, for initiating
switching actions,
such as "coolant ON",
maximum five M functions per
block.
M...
M0 Programmed stop The machining is stopped at the
end of a block containing M0; to
continue, press NC START.
M1 Optional stop As with M0, but the stop is only
performed if a special signal
(Program control: "M01") is
present.
M2 End of main program with return to
beginning of program
Can be found in the last block of
the processing sequence
M30 End of program (as M2) Can be found in the last block of
the processing sequence
M17 End of subroutine Can be found in the last block of
the processing sequence
M3 CW rotation of spindle
M4 CCW rotation of spindle
M5 Spindle stop
