Up to three M functions can be programmed in one traversing block, with
any assignment of M1, M2 and M3. The output sequence of the M functions
is always M1

M3 (for information about output see Section 9.1).
The following figure shows an example.

M0, M2, M18 and M30 are always output at the end of the traversing move-
ment.
M0, M2, M18 and M30 are mutually exclusive within a single block.
If M no. 0 is programmed in a traversing block, the program stops at the end
of the traversing block and M0 is output. Only a new START edge causes the
traversing program to be continued.
If M2 or M30 is programmed in a block, then after positioning is complete
the M function is output with a subsequent programmed stop and a jump
back to the start of the program. The Start edge can restart the program. M2
or M30 is always the last output in the block.
If the program is called up as a subprogram, the action skips to the main pro-
gram. In this case M2 or M30 is not output.
