8.2 Alarm/Warning Limits

8.2.1 Warnings and Alarm Messages

There is a clear distinction between alarms and warnings. In the event of 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 for the frequency converter to start operating again. A warning on the other
hand may come when a warning condition appears, and disappear when conditions return to normal without interfering with the process.

8.2.2 Warnings

All warnings within the frequency converter are represented by a single bit within a warning word. A warning word is always an action parameter. Bit status FALSE
[0] means no warning, while bit status TRUE [1] means warning. To each bit and each bit status there is a corresponding text string. In addition to the warning
word message the master will also be notified through a change of bit 7 in the Status Word.

8.2.3 Alarms

Following an Alarm message, the frequency converter will enter Fault condition. Only after the fault has been alleviated and the master has acknowledged the
alarm message by setting bit 3 in the Control Word, can the frequency converter resume operation. All alarms within the frequency converter are represented by
a single bit within an alarm word. An alarm word is always an action parameter. Bit status FALSE [0] means no alarm, while bit status TRUE [1] means alarm.
