8.5 Extended Diagnosis
Receive the extended diagnosis function, alarm, and
warning information from the frequency converter. The
setting of parameter 8-07 Diagnosis Trigger determines
which frequency converter events trigger the extended
diagnosis function:
•
When parameter 8-07 Diagnosis Trigger is set to [0]
Disable, no extended diagnosis data is sent
regardless of whether it appears in the frequency
converter or not.
•
When parameter 8-07 Diagnosis Trigger is set to [1]
Alarms, extended diagnosis data is sent when 1
or more alarms arrive in the alarm
parameter 16-90 Alarm Word or
parameter 9-53 Probus Warning Word.
When parameter 8-06 Reset Control Word Timeout is set to
[2] Alarms/Warnings, extended diagnosis data is sent if 1 or
more alarms/warnings arrive in the alarm
parameter 16-90 Alarm Word or parameter 9-53
Probus
Warning Word, or in the warning parameter 16-92 Warning
Word.
The extended diagnosis sequence is as follows:
If an alarm or warning appears, the frequency converter
sends a high-priority message to the master via the output
data telegram. The master then sends a request for
extended diagnosis information, to which the frequency
converter replies. When the alarm or warning disappears,
the frequency converter again sends a message to the
master, and on the following request from the master,
returns a standard DP diagnosis frame (6 bytes).
