Function:
Disable: Extended diagnosis data are not sent
even if they appear in the frequency converter.
Trigger on alarms: Extended diagnosis data are
sent when one or more alarms appear in alarm
par. 16-04 or 9-53.
Trigger alarms/warn: Extended diagnosis data
are sent if one or more alarms/warnings appear
in alarm par. 16-04, 9-53, or warning parameter
16-05.
Alarm diagnostics: The extended diagnosis
sequence works as follows: If an Alarm or
warning appears, the frequency converter
informs the master by sending a high priority
message via the output data telegram.
Consequently, the master sends a request for
extended diagnosis information to the frequency
converter. The frequency converter replies.
When the Alarm/warning disappears, the
frequency converter informs the master again,
and on the following request from the master
returns a standard DP diagnosis frame (6 bytes).
The content of the extended diagnosis frame is as follows:
Byte Content Description
