7.1.2 Alarm Word and Warning Word

Alarm word and warning word are shown in the display in Hex format. If there is more than one warning or alarm, a sum of all warnings or alarms will be shown.

Warning word and alarm word are displayed in par. DR-90 to DR-95. For more information on the individual alarms and warnings, please refer to: AF-650 GP/

AF-600 FP Design Guide.

NB!

Please note that the availability of the individual alarms and warnings are dependent on the drive type: AF-600 FP/AF-650 GP series.

Warning 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 must acknowledge the alarm message in order to start operation of the frequency converter again. A warning, on the other

hand, may appear when a warning condition arises, then disappear when conditions return to normal without interfering with the process.

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. Each bit status has a corresponding text string message. In addition to the warning word message

the master will also be notified via a change in the status word.
