DB21, ...
DBX7.2
NC STOP at block limit
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
The current NC program is stopped after the current part program block has been completely
processed. Otherwise, as for DB21, ... DBX7.3 (NC stop).
Signal state 0 or
edge change
1 → 0
No effect.
Corresponds to .... DB21, ... DBX7.3 (NC stop)
DB21, ... DBX7.4 (NC stop, axes plus spindles)
DB21, ... DBX35.2 (program status stopped)
DB21, ... DBX35.6 (channel status interrupted)
DB21, ...
DBX7.3
NC STOP
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
AUTOMATIC or MDA mode:
Processing of the part program active in the channel is stopped.
The axes (not spindles) are brought to a standstill within the assigned acceleration parameters.
• Program status: stopped
• Channel status: interrupted
JOG mode:
In JOG mode, incompletely traversed incremental paths (INC...) are retracted at the next NC
START.
Note
The signal must be present for at least one PLC cycle (OB1).
Signal state 0 or
edge change
1 → 0
No effect.
Signal irrelevant for
...
• Program status: aborted
• Channel status: Reset
Special cases,
errors, ......
• If data are transferred to the NCK after NC STOP (e.g., tool offset), the data are cleared at the
next NC START.
Corresponds to .... DB21, ... DBX7.2 (NC STOP at block limit)
DB21, ... DBX7.4 (NC STOP axes plus spindles)
DB21, ... DBX35.2 (program status stopped)
DB21, ... DBX35.6 (channel status interrupted)
