9.2 Alarms
Inverter with CU240B-2 and CU240E-2 Control Units
248 Operating Instructions, 01/2011, FW 4.4, A5E02299792B AB
9.2 Alarms
Alarms have the following properties:
They do not have a direct effect in the inverter and disappear once the cause has been
removed
They do not need have to be acknowledged
They are signaled as follows
Status display via bit 7 in status word 1 (r0052)
at the Operator Panel with a Axxxxx
via STARTER, if you click on TAB
at the bottom left of the STARTER screen
In order to pinpoint the cause of an alarm, there is a unique alarm code and also a value for
each alarm.
Alarm buffer
For each incoming alarm, the inverter saves the alarm, alarm value and the time that the
alarm was received.

Figure 9-1 Saving the first alarm in the alarm buffer
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 an internal time calculation to save the alarm times. More information on
the internal time calculation can be found in Chapter System runtime (Page 181).
As soo
n 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 Saving the second alarm in the alarm buffer
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.
