8.2.6. Warning and Alarm Messages
There is a clear distinction between alarms and warnings. When there is an alarm, the frequency
converter will enter a fault condition. After the cause for the alarm has been cleared, the master
will have to acknowledge the alarm message before the frequency converter can start operating
again. A warning, on the other hand, may come when a warning condition appears, then disappear
when conditions return to normal, without interfering with the process.
Warnings
Warnings within the frequency converter are represented by a single bit within a warning word.
A warning word is always an active parameter. Bit status FALSE [0] means no warning, while bit
status TRUE [1] means warning. Any bit change in the warning word will be notified by a change
of bit 7 in the status word.
