566 Fault tracing
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 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.
Warning and fault indications can be directed to a relay output or a digital input/output
by selecting Warning, Fault or Fault (-1) in the source selection parameter. See
sections
• Programmable digital inputs and outputs (page 64)
• Programmable relay outputs (page 65), and
• Programmable I/O extensions (page 65).
Pure events
In addition to warnings and faults, there are pure events that are only recorded in the
event logs of the drive. The codes of these events are included in the Warning
messages table.
Editable messages
For some warnings and faults, the message text can be edited and instructions and
contact information added. To edit these messages, choose Menu - Settings - Edit
texts on the control panel.
Warning/fault history and analysis
Event logs
The drive has two event logs that can be accessed from the main Menu on the control
panel. The logs 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 64 most recent events. All
indications are stored in the event logs with a time stamp and other information.
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.
Factory data logger
The drive has a data logger that samples preselected drive values at 500-
microsecond (default; see parameter 96.65 Factory data logger time level) intervals.
By default, approximately 700 samples recorded immediately before and after a fault
