4 Programming
4.8 Entering Miscellaneous Functions and STOP
Some M functions are not effective on certain machines. The machine tool builder may also
add some of his own M functions. See your machine tool manual.
The M functions (M for miscellaneous) affect:
• Program run
• Machine function
• Tool behavior
On the inside back cover of this manual you will find a list of M functions
that are predetermined for the TNC. The list indicates whether an
M function begins at the start, or at the end of the block in which it is
programmed.
Answer the following requests in a positioning block:
MISCELLANEOUS FUNCTION M?
Enter the miscellaneous function, for example M3 (spindle ON,
clockwise rotation).
To enter an M function in a STOP block:
MISCELLANEOUS FUNCTION M?
Enter the miscellaneous function, for example M5 (spindle STOP).
Resulting NC block: STOP M5
If the M function was programmed in a STOP block, program run will be
interrupted at that block.
Some M functions are not effective on certain machines. The machine tool builder may also
add some of his own M functions.
A program run or test run is interrupted when it reaches a block contain-
ing the STOP function.
An M function can be programmed in a STOP block.
If you wish to interrupt the program run or program test for a certain
duration, use the cycle 9: DWELL TIME (see page 8-56).
To enter a STOP function:
Press the STOP key.
MISCELLANEOUS FUNCTION M ?
Enter an M function, if desired, for example M6 (tool change).
Resulting NC block: STOP M6
