Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
16939 [Channel %1: ] Action %2<ALNX> rejected due to active gear change
Parameters: %1 = Channel ID
%2 = Action number/action name
Definitions: Reorganization events that are possible in Stop state, e.g mode change, are waiting for the end of the
gear change. However, the maximum waiting period has elapsed.
Reaction: Interface signals are set.
Alarm display.
Remedy: Repeat action or increase MD10192 $MN_GEAR_CHANGE_WAIT_TIME.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
16940 [Channel %1: ] Action %2<ALNX> wait for gear change
Parameters: %1 = Channel ID
%2 = Action number/action name
Definitions: Reorganization events are waiting for the end of a gear change. The alarm is displayed during the
waiting period.
Reaction: Alarm display.
Warning display.
Remedy: Alarm is suppressed by means of MD11411 $MN_ENABLE_ALARM_MASK bit 1 = 0.
Program Con- Alarm display showing cause of alarm disappears. No further operator action necessary.
tinuation:
16941 [Channel %1: ] Action %2<ALNX> rejected because no program event
has been executed yet
Parameters: %1 = Channel ID
%2 = Action number/action name
Definitions: The setting of the MD20108 $MC_PROG_EVENT_MASK forces an asynchronous subprogram to be
triggered automatically on RESET or PowerOn. The implicitly triggered asynchronous subprograms
are normally called "Event-triggered program call" or "Program event".
In the alarm situation, this asynchronous subprogram could not yet be activated; that is why the action
(normally start of part program) must be rejected.
Reasons for the fact that the asynchronous subprogram could not be triggered:
1. The asynchronous subprogram does not exist (/_N_CMA_DIR/_N_PROG_EVENT_SPF)
2. The asynchronous subprogram is allowed to start in the referenced state only (see MD11602
$MN_ASUP_START_MASK)
3. READY is missing (because of alarm)
Reaction: Alarm display.
Remedy: Load program
Check MD11602 $MN_ASUP_START_MASK
Acknowledge alarm
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
16942 [Channel %1: ] Start program command action %2<ALNX> not possible
Parameters: %1 = Channel ID
%2 = Action number/action name
Definitions: Currently, the alarm occurs only in combination with the SERUPRO action. SERUPRO stands for
search via program test.
SERUPRO is currently searching the search target and has therefore switched this channel to the pro-
gram test mode. With the START program command in channel 1, another channel 2 would actually
be started, which means that axes would really be started during the search action.
If this alarm is switched off (see help), the user can make use of the above behavior by initially select-
ing via PLC the program test mode in channel 2, leaving channel 2 executing until its natural end, stop-
ping channel 2 in order to deselect program test again.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
