Test Run and Program Run
16.5 Program run
Program-controlled interruptions
You can define interruptions directly in the machining program. The
control interrupts the program run in the NC Block containing one
of the following inputs:
Programmed stop G38 (with and without miscellaneous
function)
Programmed stop M0
Conditional stop M1
Danger of collision!
The control loses modally affective program
information and therefore contextual references after
the following handling:
Cursor movement to another NC block
The jump command GOTO to another NC block
Editing an NC block
Loss of this contextual reference may cause
undesired tool positions!
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.
