M5
Spindle stop
Mn=3 CW rotation of spindle n = 1 M1=3 ; CW rotation stop
for spindle 1
Mn=4 CCW rotation of spindle (for spindle n) n = 1 M1=4 ; CCW rotation stop
for spindle 1
Mn=5 Spindle stop (for spindle n) n = 1 M1=5 ; Spindle stop for
spindle 1
M6 Tool change Only if activated with M6 via the
machine control panel; other-
wise, change directly using the T
command
M40
Automatic gear stage switching
Mn=40 Automatic gear stage switching (for spindle
n)
n = 1 M1=40 ; automatic gear
stage; for spindle 1
M41 to M45
Gear stage 1 to gear stage 5
Mn=41 to
Mn=45
Gear stage 1 to gear stage 5 (for spindle n) n = 1 M1=41; 1st gear stage for
spindle 1
M19
Spindle positioned at 0 degree
M70
Spindle switched to the axis mode
M... Remaining M functions Functionality is not defined by
the control system and can
therefore be used freely by the
machine manufacturer
N Block number - sub-
block
0 ... 9999 9999
only integer, no
sign
Can be used to identify blocks
with a number; is written at the
beginning of a block.
N20
: Block number of a
main block
0 ... 9999 9999
only integer, no
sign
Special block identification, used
instead of N... ; such a block
should contain all instructions for
a complete subsequent machin-
ing step.
:20
P Number of subroutine
passes
1 ... 9999
only integer, no
sign
Is used if the subroutine is run
several times and is contained in
the same block as the call
L781 P... ;separate block
N10 L871 P3 ; three cy-
cles

Arithmetic functions In addition to the 4 basic arith-
metic functions using the oper-
ands + - * /, there are the
following arithmetic functions:
SIN( )
Sine
Degrees
R1=SIN(17.35)
COS()
Cosine
Degrees
R2=COS(R3)
TAN()
Tangent
Degrees
R4=TAN(R5)
