Program-controlled interruptions
You can set interruptions directly in the NC program. The control
interrupts the program run in the NC Block containing one of the
following inputs:
Programmed stop
STOP
(with and without miscellaneous
function)
Programmed stop
M0
Conditional stop
M1
NOTICE
Danger of collision!
Certain manual interactions cause the control to lose program
information affecting the mode and thereby to lose the so-called
contextual reference. After the loss of the contextual reference,
unexpected and undesired movements can occur. There is a
danger of collision during subsequent machining operations!
Do not perform the following interactions:
Cursor movement to another NC block
The jump command
GOTO
to another NC block
Editing an NC block
Modifying Q parameter values with the
Q INFO
soft key
Switching the operating modes
Restore the contextual reference via repetition of the required
NC blocks
Refer to your machine manual.
The miscellaneous function
M6
may also lead to
a suspension of the program run. The machine
manufacturer sets the functional scope of the
miscellaneous functions.
