Value assignments
The machining is stopped at the end of a block
containing M0; to continue, press NC START.
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
Reserved; do not use
Reserved; do not use
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 freely by the machine
manufacturer
0 ... 9999 9999 Can be used to identify blocks with a number;
only integer, without sign is written in the beginning of a block
0 ... 9999 9999 Special block identification, used instead of N... ; such
only integer, without sign a block should contain all instructions for a complete
subsequent machining step.
1 ... 9999 Is used if the subroutine is run several times and is
only integer, without sign contained in the same block as the call
