Warning/Fault History - ABB ACS880 Firmware Manual

176 Fault tracing

Warning/fault history

Event log

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. All indications
are stored in the event logs 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.
Auxiliary code
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.
Factory data logger
The DC/DC converter has a data logger that samples preselected values at
500-microsecond (default; see parameter
By default, approximately 700 samples recorded immediately before and after a fault are
saved to the memory unit of the DC/DC converter. 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.)
The values that are recorded in the factory data log are
102.01 DC voltage,
word 1, 106.01 Main control
102.07 W phase current. The selection of parameters cannot be changed by the user.
Other data loggers

User data logger
A custom data logger can be configured using the Drive composer pro PC tool. This
functionality enables the free selection of up to eight parameters to be sampled at
selectable intervals. The triggering conditions and the length of the monitoring period can
also be defined by the user within the limit of approximately 8000 samples. In addition to
the PC tool, the status of the logger is shown by parameter
word. The triggering sources can be selected by parameters
trigger and 196.64 User data logger
saved to the memory unit for later analysis.
PSL2 data logger
The BCU control unit used with certain DC/DC converter types (especially those with
parallel-connected DC/DC converter modules) contains a data logger that collects data
from the modules to help fault tracing and analysis. The data is saved onto the SD memory
card attached to the BCU, and can be analyzed by ABB service personnel.
Parameters that contain 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 groups
