328 Fault tracing
Indications

Warnings and faults
Warnings and faults indicate an abnormal drive status. The codes and names of
active warnings and faults are displayed on the control panel of the drive as well
as in the Drive composer PC tool. Only the codes of warnings and faults are
available over fieldbus.
Warnings do not need to be reset; they stop showing when the cause of the
warning ceases. Warnings do not latch and the drive will continue to operate the
motor.
Faults latch inside the drive and cause the drive to trip, and the motor stops.
After the cause of a fault has been removed, the fault can be reset from
parameter 31.11 Fault reset selection (such as the control panel, Drive composer
PC tool, the digital inputs of the drive, or fieldbus). Reseting the fault creates an
event 64FF Fault reset . After the reset, the drive can be restarted.
Note that some faults require a reboot of the control unit either by switching
the power off and on, or using parameter 96.08 Control board boot – this is
mentioned in the fault listing wherever appropriate.
 Pure events
In addition to warnings and faults, there are pure events that are only recorded
in the event log of the drive. The codes of these events are included in the
Warning messages table on page 330 .
Warning/fault history

Event log
All indications are stored in the event log. The event log stores information on
•
the last 8 fault recordings, that is, faults that tripped the drive or fault resets
•
the last 10 warnings or pure events that occurred.
See section Viewing warning/fault information on page 329 . The logs can be
cleared using parameter
96.51 Clear fault and event logger
.
Auxiliary codes
Some events generate an auxiliary code that often helps in pinpointing the
problem. On the control panel, the auxiliary code is stored as part of the details
of the event; in the Drive composer PC tool, the auxiliary code is shown in the
event listing.
