11.1 Entering miscellaneous functions M and
STOP
Fundamentals
With the control’s miscellaneous functions—also called M
functions—you can affect:
the program run, e.g. a program interruption
the machine functions, such as switching spindle rotation and
coolant supply on and off
the path behavior of the tool
You can enter up to four M (miscellaneous) functions at the end of
a positioning block or in a separate block. The control displays the
following dialog question:
Miscellaneous function M ?
You usually enter only the number of the miscellaneous function
in the programming dialog. Some miscellaneous functions can be
programmed with additional parameters. In this case, the dialog is
continued for the parameter input.
In the
Manual operation
and
Electronic handwheel
operating
modes, the M functions are entered with the
M
soft key.
