Sinumerik Alarm 16950 Channel %1 search run with hold block
%1 = Channel ID
Informational alarm.The search run was not performed on the interruption block, instead, it touches down shortly before that. This so-called “hold block” is generated by the part program command IPTRLOCK, or implicitly defined by $MC_AUTO_IPTR_LOCK. This is to preven you from performing a search run in critical program areast (e.g. gear hobbing).The alarm also displays that, instead of searching for the block that actually was interrupted before, another block is being searched for. This behavior is desired and the alarm serves only informational purposes.
