Overview of Alarms
NCK alarms
16943 Channel %1 action %2<ALNX> not possible due to ASUP
Parameters: %1 = Channel ID
%2 = Action number/action name
Definitions: The action in the 2nd parameter was rejected, since an asynchronous subprogram is currently active.
Currently, only the integrated search run is rejected with this alarm. The integrated search run is
activated, if search run is triggered in the Stop program state. In other words: Parts of a program have
already been executed and a following program part is "skipped" with search run in order to continue
the program afterwards.
The event is not possible if the program is stopped within an asynchronous subprogram or if an
asynchronous subprogram had been selected before the event. An asynchronous subprogram is
selected, when the triggering asynchronous subprogram event arrives, but the asynchronous
subprogram cannot be started (e.g. the asynchronous start program is not started because of a read-
in disable or because the Stop key is active).
In this case, it is irrelevant whether a user ASUP or a system ASUP has been triggered. User ASUPs
are activated via FC-9 or via the fast inputs.
The following events lead to system ASUPS:
- Mode change
- Overstore on
- Aborting subprogram level
- Switching on of single block, type 2
- Setting machine data effective
- Setting user data effective
- Change skip levels
- Dry run on/off
- Program test off
- Correction block alarms
- Editing modi in Teach
- External zero offset
- Axis replacement
- Delete distance-to-go
- Measuring
Reaction: Alarm display.
Remedy: Repeat the action after the end of the asynchronous subprogram.
Program Clear alarm with the Delete key or NC START.
Continuation:
16944 Channel %1 action %2<ALNX> not possible due to active search blocks
Parameters: %1 = Channel ID
%2 = Action number/action name
Definitions: The NCK is currently processing either the action blocks of the search run or the approach motion after
the search run.
In this situation, the action (2nd parameter of the alarm) must be rejected.
Currently, only the integrated search run is rejected with this alarm. The integrated search run is
activated, if search run is triggered in the Stop program state. In other words: Parts of a program have
already been executed and a following program part is "skipped" with search run in order to continue
the program afterwards.
Reaction: Alarm display.
Remedy: Repeat the action after the approach motion of the search run.
Program Clear alarm with the Delete key or NC START.
