9.5 Alarms, alarm buer, and alarm history
Overview
An alarm generally indicates that the converter may no longer be able to maintain the operation
of the motor in future.
The extended diagnostics have an alarm buer and an alarm history, in which the converter
stores the most recent alarms.
Function description
Alarms have the following properties:
• Incoming alarms have no direct inuence on the converter.
• A warning disappears as soon as its cause is eliminated.
• Alarms do not have to be acknowledged.
Alarm code or alarm value describe the cause of the alarm.

Figure 9-2 Alarm buer
The converter saves incoming alarms in the alarm buer. An alarm includes an alarm code, an
alarm value, and two alarm times:
• Alarm code: r2122
• Alarm value: r2124 in xed-point format "I32", r2134 in oating-point format "Float"
• Alarm time received = r2145 + r2123
• Alarm time removed = r2146 + r2125
The converter takes its internal time calculation to save the alarm times.
System runtime (Page 349)
Up to 8 alarms can be saved in the alarm buer.
In the alarm buer, the alarms are sorted according to "Alarm time received". If the alarm buer
is completely lled and an additional alarm occurs, then the converter overwrites the values with
Index [7].
