Reactions: - Alarm display.
Remedy: Repeat the action after the end of the asynchronous subprogram.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
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.
Reactions: - Alarm display.
Remedy: Repeat the action after the approach motion of the search run.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
16945
Channel %1 action %2<ALNX> delayed up to the block end
Parameters: %1 = Channel ID
%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.
Reactions: - Alarm display.
Remedy: Alarm can be switched off via $MN_SUPPRESS_ALARM_MASK bit 17==1.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
16946
Channel %1 start via START is not allowed
Parameters: %1 = Channel ID
