Pending messages
If a message has occurred and been acknowledged but has not gone, this message
will be listed in the Pending Messages menu. All current messages can be displayed in
the Diagnosis menu under Pending Messages (2-1). Active warnings and alerts can
also be connected to the relay outputs.
Message history
Only messages that have come, been acknowledged, and gone are listed in the
message history. The message history can be viewed by selecting the Message History
parameter 2-2. The last 100 messages are listed here. You can use the arrow keys and
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
You can acknowledge the message once the cause has been rectified. Messages can
be acknowledged separately 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16: Acknowledgement types for messages
Property of message Type of acknowledgement
Self-acknowledging Message self-acknowledges if condition for message has gone.
Self-acknowledging
(configurable)
Users can choose between self-acknowledging and acknowledging manually.
Partially self-
acknowledging
Alerts that are partially self-acknowledging carry out self-acknowledgement in
increasingly large intervals after the alarm condition has gone. If the alert occurs
repeatedly within a specific time window, no additional self-acknowledgement is
carried out.
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, self-
acknowledgement no longer takes place.
Non-self-acknowledging 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.
