Effectiveness of miscellaneous functions
Please note that some M functions become effective at the start
of a positioning block, and others at the end, regardless of their
position in the NC block.
M functions come into effect in the block in which they are called.
Some M functions are effective only in the block in which they are
programmed. Unless the miscellaneous function is only effective
blockwise, either you must cancel it in a subsequent block with a
separate M function, or it is automatically canceled by the TNC at
the end of the program.
If several M functions are programmed in one NC
block, then the execution sequence is as follows:
M functions taking effect at the start of the block
are executed before those taking effect at the end
of the block
If all M functions take effect at the start or end
of block, execution take place in the sequence
programmed
Entering a miscellaneous function in a STOP block
If you program a
STOP
block, the program run or test run is
interrupted at the block, e.g. for a tool inspection. You can also
enter an M (miscellaneous) function in a
STOP
block:
To program an interruption of program run, press
the
STOP
key
