Overview of Alarms
Example: It is not permissible to activate block search via program test (PI service
_N_FINDBL with mode parameter 5) when program test is active.
Reactions: - Alarm display.
Remedy: Deactivate program test.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
16938
Channel %1 action %2<ALNX> aborted due to active gear change
Parameters: %1 = Channel ID
%2 = Action number/action name
Definitions: Reorganization events are, among others, subprogram abort, delete distance-to- go and
interrupts, axis replacement, exiting the correction state. These events wait for the end of
a gear change. However, the maximum waiting period has elapsed.
Reactions: - NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Program must be aborted with Reset and, if necessary, GEAR_CHANGE_WAIT_TIME
must be increased.
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.
Reactions: - Interface signals are set.
- Alarm display.
Remedy: Repeat action or increase MD 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.
Reactions: - Alarm display.
- Warning display.
Remedy: Alarm is suppressed by means of 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 exe-
cuted yet
Parameters: %1 = Channel ID
%2 = Action number/action name
Definitions: The setting of the machine data $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 "Pro-
gram event".
