Alarms have the following properties:
● They do not have a direct effect in the converter 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.
For each incoming alarm, the converter saves the alarm, alarm value and the time that the
alarm was received.
