 Extended Diagnosis
Using the extended diagnosis fun ction, alarm and warning information can be received from the frequency
converter. The setting of par. 8-07 Diagnosis trigger determines which frequency converter events should
trigger the extended diagnosis function.
When par. 8-07 Diagnosis trigger is set to Disable [0], no extended diagnosis data are sent regardless of
whether they appear in the frequency converter.
When par. 8-07 Diagnosis trigger is set to Alarms [1], extended diagnosis data are sent when one or more
alarms arrive in the alarm par. 16-90 Alarm word or 9-53 Warning word.
When par. 8-06 is set to Alarms/Warnings [2], extended diagnosis data are sent if one or more
alarms/warnings arrive in the alarm par. 16-90 Alarm word or 9-53 Warning word, or in the warning par.
16-92 Warning word.
The extended diagnosis sequence is as follows: If an alarm or warning appears, the frequency converter
will indicate that to the master by sending a high priority message via the output data telegram. This will
cause the master to send a request for extended diagnosis information to the frequency converter, to
which the frequency converter will reply. When the alarm or warning disappears, the frequency converter
will again indicate that to the master, and on the following request from the master, return a standard
DP diagnosis frame (6 bytes).
