4.6.2 Advanced SmartWire-DT diagnostics

4.6.2.1 Advanced SmartWire-DT diagnostics via PROFIBUS
86
When there is a collective diagnostic (input byte 0, bit 4 (DIAG)), the variable
frequency drive/variable speed starter will provide advanced diagnostic
messages.
The following messages are generated by the variable frequency drive/
variable speed starter.

Value Meaning
[hex]
14 Internal communication
problem in the variable
frequency drive/variable
speed starter
15 no unambiguous position
of the 1-0-A switch for
more than 4 seconds
19 There is a warning at
hand for the variable
frequency drive/variable
speed starter.
1A There is a fault at hand on
the variable frequency
drive/variable speed
starter.
Diagnostic alarm 15
If the 1-0-A switch does not assume a clear position for longer than
4 seconds, the variable frequency drive/variable speed starter will be
switched off and generate the following error messages:
• DIAG,
• ERR,
• Diagnostic alarm 15
In addition, the SmartWire-DT diagnostic LED on the DX-NET-
SWD...SmartWire-DT connection will flash green (frequency: 3 Hz).

Remedy
• If the error continues, switch
the supply voltage off/on
• Check EMC
• Replace the variable
frequency drive/variable
speed starter
Move the 1-0-A switch to one of
the three defined positions.
Read warning PNU 860.0 and fix
