Explanation:
This alarm is active with "Group Serupro" only. "Group Serupro" is activated by means of MD10708
$MN_SERUPRO_MODE, bit 2 and enables the retrace support of entire channel groups during block search.
A _dependent channel_ is a channel that had indirectly been started by the currently active channel. The currently active
channel was started via PLC.
This channel m_u_s_t be terminated (i.e. reached M30) before the current channel is terminated.
This alarm occurs if the currently active channel is terminated before the dependent channel.
Reaction:
Alarm display.
Remedy:
Switch off "Group Serupro" (see MD10708 $MN_SERUPRO_MASK) or install WAITE.
Programm
continuation:
Clear alarm with the Delete key or NC START.

[Channel %1: ] Search run with hold block
Parameters:
%1 = Channel number
Explanation:
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 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.
Reaction:
Alarm display.
Remedy:
MD11410 $MN_SUPPRESS_ALARM_MASK, MD22680 $MC_AUTO_IPTR_LOCK and language command IPTRLOCK
Programm
continuation:
Clear alarm with the Delete key or NC START.
16951
[Channel %1: ] Search run in a protected program section.
Parameters:
%1 = Channel number
Explanation:
A part programmer can define protected part program sections with the language commands IPTRLOCK and
IPTRUNLOCK. Every search run in these program sections will then be acknowledged with alarm 16951. In other words:
When the alarm appears, the user has started a search run (Serupro type) and the search target lies in a protected area.
A protected area can also be defined implicitly with the MD22680 $MC_AUTO_IPTR_LOCK.
Note:
The alarm can only be generated if the simulation has been completed during the search run. The alarm cannot be output
immediately at the start of the search run.
Reaction:
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy:
MD11410 $MN_SUPPRESS_ALARM_MASK, MD22680 $MC_AUTO_IPTR_LOCK and language command IPTRLOCK
Programm
continuation:
Clear alarm with the RESET key. Restart part program
16952
[Channel %1: ] Start program command not possible due to MDI
Parameters:
%1 = Channel number
Explanation:
NCK is currently executing an ASUB in MDI mode. In this constellation, parts program command "Start" is not allowed for
another channel. Attention: If an ASUB is started from JOG, the NCK can internally change to MDI, if the NCK was
previously in MDI and not in RESET. Note: Without this alarm, the MDI buffer of the other channel would always be started.
Reaction:
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy:
Start ASUB in AUTO or ->JOG in AUTO
Programm
continuation:
Clear alarm with the RESET key. Restart part program
