Value assignments Information
7 decimals; Instead of a free name, it is
integer only, no sign 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.
0 ... 99 For example, for initiating
only integer, no sign switching actions, such as
"coolant ON", maximum five M
functions per block.
The machining is stopped at
the end of a block containing
M0; to continue, press the
following key:
As with M0, but the stop is
only performed if a special
signal (Program control:
"M01") is present.
Can be found in the last block
of the processing sequence
Can be found in the last block

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