parameter

the OK key to select an entry from the list.
Acknowledging and resetting messages
NOTE
Depending on the combination of settings, the frequency inverter could
conceivably restart automatically after acknowledgement/reset or when the cause
of the malfunction or fault has been eliminated.
Acknowledgement Messages can be acknowledged once the cause has been rectified. Messages can be
acknowledged individually in the Diagnosis menu. A message can also be
acknowledged via a digital input. Digital input 2 is defaulted for this purpose.
Overview of warnings and alerts
Messages can be acknowledged as follows:
Table 19: Acknowledgement types for messages
Property of message Type of acknowledgement
Self-acknowledging Message is automatically acknowledged if condition for message no longer applies.
Automatic
acknowledgement
(configurable) Users can choose between automatic acknowledgement and manual
acknowledgement.
Partially automatic
acknowledgement Alerts that are partially acknowledged automatically carry out automatic
acknowledgement in increasingly large intervals after the alert condition no longer
applies. If the alert occurs repeatedly within a specific time window, automatic
acknowledgement is suspended.
As soon as the alarm condition of a pending alert no longer exists, the time interval is
started. When this interval expires, automatic acknowledgement takes place.
If the alert occurs again within 30 seconds after the time interval has started, the
interval is extended by one increment. Should this not be the case, the previous
(shorter) time interval is reverted to and corresponding action is taken again in
30 seconds. The time intervals are 1 second, 5 seconds, 20 seconds, and endless (i.e.
manual acknowledgement is required). When the 20-second interval is extended,
automatic acknowledgement no longer takes place.
No automatic
acknowledgement Must be acknowledged manually.
Time stamp If a message is not acknowledged and its condition comes and goes several times in
this time window, the first occurrence of the message is always used for the Message
Come time stamp. The Message Condition Gone time stamp, however, always shows
the last time the message condition was no longer active.
