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
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 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 $MN_SUPPRESS_ALARM_MASK bit 17==1.
Program Clear alarm with the Delete key or NC START.
Continuation:
16946 Channel %1 start via START is not allowed
Parameters: %1 = Channel ID
Definitions: This alarm is active with "Group Serupro" only. _Group Serupro" is activated by means of
"$MC_SERUPRO_MODE BIT2" and enables the retrace support of entire channel groups during
block search.
The machine data $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
$MC_DISABLE_PLC_START==FALSE was set.
Reaction: Alarm display.
Remedy: Modify $MC_DISABLE_PLC_START of switch off "Group Serupro" (see $MC_SERUPRO_MODE).
Program Clear alarm with the Delete key or NC START.
Continuation:
16947 Channel %1 start via PLC is not allowed
Parameters: %1 = Channel ID
Definitions: This alarm is active with "Group Serupro" only. _Group Serupro" is activated by means of
"$MC_SERUPRO_MODE BIT2" and enables the retrace support of entire channel groups during
block search.
The machine data $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 $MC_DISABLE_PLC_START==TRUE
was set.
Reaction: Alarm display.
Remedy: Modify $MC_DISABLE_PLC_START of switch off "Group Serupro" (see $MC_SERUPRO_MODE).
Program Clear alarm with the Delete key or NC START.
