406 Fault tracing
How to reset faults
After the cause of a fault has been corrected, the fault can be reset from a selectable
source (see parameter 31.11 Fault reset selection) such as the control panel, Drive
composer PC tool, the digital inputs of the drive, or fieldbus. After the fault is
removed, the drive can be restarted.
Warning/fault history
Event logs
When a warning or fault is detected, it is stored in the event log with a time stamp and
other information. The event log can be accessed from the main Menu on the control
panel. It can also be accessed (and reset) using the Drive composer PC tool.
One of the logs contains faults and fault resets. The other log lists warnings and pure
events, as well as clearing entries. Both logs contain 32 most recent events.
Auxiliary codes
Some events generate an auxiliary code that often helps in pinpointing the
problem.The auxiliary code is displayed on the control panel together with the
message. It is also stored in the event log details. In the Drive composer PC tool, the
auxiliary code (if any) is shown in the event listing.
Parameters warning/fault information
The codes of active warnings and faults (maximum five each), and five previously
occurred warnings and faults are stored in the parameters of group 04 Warnings and
faults (page 109).
Event word (parameters 04.40...04.72)
Parameter 04.40 Event word 1 can be configured by the user to indicate the status of
16 selectable events (ie. faults, warnings or pure events). It is possible to specify an
auxiliary code for each event to filter out other auxiliary codes.
