4.1 Warnings and Alarms
NOTICE
Refer to the relevant operating instructions for an
overview of warning and alarm types and for the full list
of warnings and alarms.
Alarm word, warning word, and PROFIBUS warning word
are shown on the frequency converter display in hex
format. When there is more than 1 warning or alarm, the
sum of all warnings or alarms is shown. Alarm word,
warning word, and PROFIBUS warning word can also be
shown via eldbus in:
•
Parameter 16-90 Alarm Word.
•
Parameter 16-92 Warning Word.
•
Parameter 9-53 Probus Warning Word.
For warning 165, Baud rate search, refer to Table 4.1.

4.2.1 LED Status
The 2 bicolour LEDs on the PROFIBUS card indicate the
status of PROFIBUS communication:
•
The lower LED (NS) indicates the net status, that
is, the cyclic communication to the PROFIBUS
master.
•
The upper LED (MS) indicates the module status,
that is, acyclic DP-V1 communication from either
a PROFIBUS master class 1 (PLC) or a master class
2 (MCT 10 Set-up Software, FDT tool).
