8.2.8 Extended Diagnostics
Using the extended diagnostics function, alarm and warning information can be received from the frequency converter. The setting of par. O-07 Diagnosis
Trigger determines which frequency converter events should trigger the extended diagnostics function.
When par. O-07 Diagnosis Trigger is set to Disable [0], no extended diagnostics data are sent regardless of whether they appear in the frequency converter.
When par. O-07 Diagnosis Trigger is set to Alarms [1], extended diagnostics data are sent when one or more alarms arrive in the alarm par. DR-90 Alarm Word
or par. PB-53 Profibus Warning Word.
When par. O-06 Reset Control Word Timeout is set to Alarms/Warnings [2], extended diagnostics data are sent if one or more alarms/warnings arrive in the alarm
par. DR-90 Alarm Word or par. PB-53 Profibus Warning Word, or in the warning par. DR-92 Warning Word.
The extended diagnostics 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 diagnostics 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 diagnostics frame (6 bytes).
The content of the extended diagnostics frame is as follows:
Byte Bit no. Name
0 to 5 Standard DP Diagnostics data
