Machine data
● Preventing stop events
In the machine data, the stopping response when G331 / G332 is active is defined:
MD11550 $MN_STOP_MODE_MASK, Bit <x> = <value>
If you always want to prevent stopping the traverse movement when G331 / G332 is active,
this area must be declared a stop delay area with the commands DELAYFSTON
and DELAYFSTOF.
Further information
Function Manual Basic Functions; Program operation, Influencing the stop events by stop
delay areas
Note
Single block
If the single block is activated in the stop delay area, the NC stops at the end of the first block
outside the stop delay area. If the single block is already selected before the stop delay area,
the NC stops at each block limit, i.e. also in the stop delay area! This deselects the stop delay
area.
Override changes
If the override is changed before a stop delay area, the override takes effect in the stop delay
area.
If the override is changed in the stop delay area, the change takes effect after the stop delay
area.
● Override
Which override is active during rigid tapping is set in:
MD12090 $MN_OVR_FUNCTION_MASK, Bit <x> = <value>
152
Bit Value Meaning
0 0 When G331 / G332 is active, stopping is not performed during a path motion or
dwell time (G4).
1 When G331 / G332 is active, stopping is performed during interruption of path
control mode, for example, by G60 or G4.
Bit Value Meaning
0 0 The spindle override is active for G331/G332
Depending on the setting in the following machine data, the override is related
either to the programmed spindle speed or to the configured spindle speed limita‐
tion:
MD12080 $MN_OVR_REFERENCE_IS_PROG_FEED
1 The path override is active for G331/G332
Depending on the setting in the following machine data, the override is related
either to the programmed path feedrate or to the configured path feedrate limitation:
MD12082 $MN_OVR_REFERENCE_IS_MIN_FEED
Note
This only applies if the limitation value is lower than the programmed path feedrate.
