cause of a fault has been removed, the fault can be reset from a selectable source
(parameter 31.11 Fault reset
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
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
messages table on page (200).


edited. To specify external events, use parameter

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.

Viewing warning/fault information
The drive is able to store a list of the active faults actually causing the drive to trip at
the present time. The drive also stores a list of faults and warnings that have
