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 immedi-
ately, 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.
Reaction: Alarm display.
Remedy: Alarm can be switched off via MD11410 $MN_SUPPRESS_ALARM_MASK bit17==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
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 pro-
gram 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 Con- Clear alarm with the Delete key or NC START.
tinuation:
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
$MN_SERUPRO_MASK).
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
16948 Channel %1 dependent channel %2 still active
Parameters: %1 = Channel ID
%2 = Channel ID
Definitions: This alarm is active with "Group Serupro" only. "Group Serupro" is activated by means of MD10708
R$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.
Program Con- Clear alarm with the Delete key or NC START.
