Overview of Alarms
NCK alarms
16955 [Channel %1: ] Stop in stop delay area is delayed
Parameters: %1 = Channel ID
Definitions: In a program area (stop delay area) that is bracketed by DELAYFSTON and DELAYFSTOF, an event
has been detected that causes a stop. The stop is delayed and executed after DELAYFSTOF. A stop
delay area can also be defined by MD11550 $MN_STOP_MODE_MASK.
Reaction: Interface signals are set.
Alarm display.
Remedy: MD11550 $MN_STOP_MODE_MASK and language command DELAYFSTON DELAYFSTOF
Program Con- Alarm display showing cause of alarm disappears. No further operator action necessary.
tinuation:
16956 [Channel %1: ] Program %2 cannot be started due to global start disable.
Parameters: %1 = Channel ID
%2 = String (path with program name)
Definitions: The program selected in this channel cannot be started as "Global start disable" had been set.
Note:
PI "_N_STRTLK" sets the "Global start disable" and PI "_N_STRTUL"
deletes the "Global start disable".
The alarm is switched on with MD11411 $MN_ENABLE_ALARM_MASK bit 6.
Reaction: Alarm display.
Remedy: Delete the "Global start disable" and restart.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
16957 [Channel %1: ] Stop-Delay area is suppressed
Parameters: %1 = Channel ID
Definitions: The program area (Stop-Delay area), which is bracketed by DELAYFSTON and DELAYFSTOF, could
not be activated. Every stop therefore becomes effective immediately and is not delayed!
This occurs every time, when braking into a stop Stop-Delay area, i.e. a braking process starts before
the Stop-Delay area and ends not earlier than in the Stop-Delay area.
If the Stop-Delay area is entered with override 0, the Stop-Delay area can also not be activated
Example: a G4 before the Stop-Delay area allows the user to reduce the override to 0. The next block
in the Stop-Delay area then starts with override 0 and the alarm situation described occurs.
MD11411 $MN_ENABLE_ALARM_MASK, bit 7 switches on this alarm.
Reaction: Interface signals are set.
Alarm display.
Remedy: MD11550 $MN_STOP_MODE_MASK and language command DELAYFSTON DELAYFSTOF
Program Con- Alarm display showing cause of alarm disappears. No further operator action necessary.
tinuation:
16959 [Channel %1: ] Action %2<ALNX> prohibited during simulation block
search.
Parameters: %1 = Channel number
%2 = Action number/action name
Definitions: The function (2nd parameter) must not be activated during simulation search.
Reaction: Alarm display.
Remedy: Wait for search end.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
16960 [Channel %1: ] Action %2<ALNX> prohibited during EXECUTE
PROGRAM AREA.
Parameters: %1 = Channel number
%2 = Action number/action name
Definitions: The function (2nd parameter) must not be activated during EXECUTE PROGRAM AREA.
Reaction: Alarm display.
Remedy: Wait for end of program area EXECUTE.
