1.12.3 Alarm List and Alarm Recognition
When a new regulation alarm is active, the Red led “Alarm” blinks on the display.
By pressing Shift + Alarm it is possible to reach the
“Alarm list” page, which lists the intervened and not yet
recognized but also the recognized and still active alarms.
In case a regulation alarm intervenes with Restart=Off (that is without an automatic restart after the alarm has
been reset), also the Sequencer (State machine) alarm gets active.
The alarm recognition can be performed by reaching the “Alarm list”, selecting the alarm to be recognized and
pressing Enter. If the alarm is recognized and inactive
, it is canceled from the list.
When all the alarms have been recognized, the Red led “Alarm” on the display il lighted (the Sequencer alarm of
the State Machine remains active).
The Red led is lighted till all the alarms become inactive and the user resets the State Machine (such commandcan
be given, for example, via the keypad with the “red” stop button).
If all the alarms on the drive have been recognized (the Red led is lighted) and a new regulation alarm intervenes,
such condition is reported with the blinking of the Red led on the display.
NOTE! It is possible to reset the regulation alarms without recognizing them. In this case the Drive is
active and the Red led blinks (no action in the alarm list has to be performed).
1.12.4 Alarm Log
This is the historic register Log, stating what happened on the Drive. It records those Drive alarms considered to
be significant. The alarm register is in the STATUS menu. It has 30 entry.
1.12.5 Alarm Configurations
In the Alarm config menu it is possible to configure the different alarms (xxx) on the following points:
xxx activity Activity to be performed in case an alarm occurs
xxx restart Restart enabling
xxx restart time Restart time
xxx hold off Hold off time
Paragraph 2.9.6 states the possible settings referring to each alarm type.
1.12.5.1 Hold Off Time
With this parameter it is possible to set the period of time, in which a specific situation has to remain active (it has
to persist) in order to be considered an alarm situation. It is possible to set a millisecond period of time, in which
the Drive does not recognize the alarm state. Therefore, the alarm is recognized only if it persists for a period
longer than the set Hold off time.
