Indications

Warnings and faults


Warnings and faults indicate an abnormal status. The codes and names of active
warnings/faults are displayed on the control panel as well as the Drive composer PC
tool. Only the codes of warnings/faults are available over fieldbus.
Warnings do not need to be reset; they stop showing when the cause of the warning
ceases. After the cause of the fault has been corrected, the active fault can be reset
from the control panel or Drive composer PC tool. The control panel can be in local or
remote (external) control mode. When the fault has been removed, the diode supply
unit can be restarted. Faults can also be reset from an external source selected by
parameter 131.11 Fault reset
Warning and fault indications can be directed to a relay output or a digital
input/output by selecting Warning,
parameter. See sections

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 diode supply unit 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 the 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 diode supply unit has a data logger that samples preselected values at
500-microsecond (default; see parameter
intervals. By default, approximately 700 samples recorded immediately before and
after a fault are saved to the memory unit of the diode supply unit. The fault data of
the last five faults is accessible in the event log when viewed in the Drive composer
pro PC tool. (The fault data is not accessible through the control panel.)
For DxT modules, the values that are recorded in the factory data log are
