Alarms, faults and system messages
9.2 Alarms
Alarm buffer
For each incoming alarm, the inverter saves the alarm, alarm value and the time that the
alarm was received.
Figure 9-1
r2124 and r2134 contain the alarm value (important for diagnostics) as "fixed point" or
"floating point" number.
The alarm times are displayed in r2145 and r2146 (in complete days) as well as in r2123 and
r2125 (in milliseconds referred to the day of the alarm). The inverter uses its internal time
calculation to save the alarm times.
As soon as the alarm has been removed, the inverter writes the associated instant in time
into parameters r2125 and r2146. The alarm remains in the alarm buffer even if the alarm
has been removed.
If an additional alarm is received, then this is also saved. The first alarm is still saved. The
alarms that have occurred are counted in p2111.
Figure 9-2
The alarm buffer can contain up to eight alarms. If an additional alarm is received after the
eighth alarm - and none of the last eight alarms have been removed - then the next to last
alarm is overwritten.
