Sinumerik Alarm 16944 Channel %1 action %2 <ALNX> not possible due to active search blocks
%1 = Channel ID
%2 = Action number/action name
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.
– Alarm display.
Repeat the action after the approach motion of the search run.
Clear alarm with the Delete key or NC START.
