Mn=3 CW rotation of spindle (for spindle n)
Mn=4 CCW rotation of spindle (for spindle n)
Mn=5 Spindle stop (for spindle n)
M6 Tool change
M40 Automatic gear stage switching
(for master spindle)
Mn=40 Automatic gear stage switching
(for spindle n)
M41 to M45 Gear stage 1 to
gear stage 5 (for master spindle)
Mn=41 to Gear stage 1 to
Mn=45 gear stage 5 (for spindle n)
M70, M19 -
M... Remaining M functions
N Block number - sub-
block
: Block number of a
main block
P Number of subrouti-
ne passes
R0 Arithmetic parame-

Arithmetic functions
SIN( ) sinusoidal
COS() Cosine
TAN() Tangent

Value assignments Information
n = 1 or = 2
n = 1 or = 2
n = 1 or = 2
Only if activated with M6 via the
machine control panel; other-
wise, change directly using the
T command
n = 1 or = 2
n = 1 or = 2
Reserved; do not use
Functionality is not defined by
the control system and can
therefore be used freely by the
machine manufacturer
0 ... 9999 9999 Can be used to identify blocks
0 ... 9, only integer, with a number;
no sign is written in the beginning of a
block
0 ... 9999 9999 Special block identification,
0 ... 9, only integer, used instead of N... ; such a
no sign block should contain all instruc-
tions for a complete subsequent
machining step.
1 ... 9999 Is used if the subroutine is run
0 ... 9, only integer, several times and is contained
no sign in the same block as the call
