Action %2 Alnx Delayed Up To The Block End; Start Via Start Is Not Allowed; Start Via Plc Is Not Allowed; Search Run With Hold Block - Siemens Sinamics S120 Diagnostic Manual

NCK alarms
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 acti-
vated 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.
Continuation:
16946 [Channel %1: ] Start via START is not allowed
Parameters: %1 = Channel ID
Definitions: This alarm is active with "Group Serupro" only. "Group Serupro" is activated by means of MD10708
$MN_SERUPRO_MASK, Bit 2 and enables the retrace support of entire channel groups during block search.
The MD22622 $MC_DISABLE_PLC_START specifies which channel is generally started from the PLC and which
channel is only allowed to be started from another channel via the START part program command.
This alarm occurs if the channel was started via the START part programm command and MD22622
$MC_DISABLE_PLC_START==FALSE was set.
Reaction: Alarm display.
Remedy: Modify MD22622 $MC_DISABLE_PLC_START of switch off "Group Serupro" (see MD10708
$MN_SERUPRO_MASK).
Program Clear alarm with the Delete key or NC START.
Continuation:
16947 [Channel %1: ] Start via PLC is not allowed
Parameters: %1 = Channel ID
Definitions: This alarm is active with "Group Serupro" only. "Group Serupro" is activated by means of MD10708
$MN_SERUPRO_MASK, Bit 2 and enables the retrace support of entire channel groups during block search.
The machine data MD22622 $MC_DISABLE_PLC_START specifies which channel is generally started from the PLC
and which channel is only allowed to be started from another channel via the START part program command.
This alarm occurs if the channel was started via the PLC and MD22622 $MC_DISABLE_PLC_START==TRUE was
set.
Reaction: Alarm display.
Remedy: Modify MD22622 $MC_DISABLE_PLC_START of switch off "Group Serupro" (see MD10708
$MN_SERUPRO_MASK).
Program Clear alarm with the Delete key or NC START.
Continuation:
16950 [Channel %1: ] Search run with hold block
Parameters: %1 = Channel number
Definitions: 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 MD22680
$MC_AUTO_IPTR_LOCK. This is to prevent you from performing a search run in critical program areas (e.g. gear hob-
bing). 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.
