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
- Canceling 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 work offset
- Axis exchange
- 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 number
%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.
Continuation:
16945 [Channel %1: ] Action %2<ALNX> delayed up to the block end
Parameters: %1 = Channel number
%2 = Action number/action name
Definitions: The currently executing action (e.g. dry run on/off, change skip levels, etc.) should be active immediately, but it can
become active not earlier than at the end of the block, since a thread is currently being machined. The action is
activated with a slight delay.
Example: Dry run is started in the middle of the thread, then traversing at high speed does not start before the next
block.
Reaction: Alarm display.
Remedy: Alarm can be switched off via MD11410 $MN_SUPPRESS_ALARM_MASK bit17==1.
Program Clear alarm with the Delete key or NC START.
