Fault tracing 499
By default, approximately 700 samples recorded immediately before and after a fault
are saved to the memory unit of the drive. 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 01.07 Motor current , 01.10
Motor torque , 01.11 DC voltage , 01.24 Flux actual % , 06.01 Main control word , 06.11
Main status word , 24.01 Used speed reference , 30.01 Limit word 1 , 30.02 Torque
limit status and 90.01 Motor speed for control . 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 drive 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 drive parameter
96.61
User data logger status word . The triggering sources can be selected by parameters
96.63 User data logger trigger and 96.64 User data logger start ). The configuration,
status and collected data is saved to the memory unit for later analysis.
PSL2 data logger
The BCU control unit used with certain drive types (especially those with parallel-
connected inverter modules) contains a data logger that collects data from the
inverter modules to help fault tracing and analysis. The data is saved onto the SD
card attached to the BCU, and can be analyzed by ABB service personnel.

Parameters that contain 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 faults are displayed in parameter group
04 Warnings and faults
(page 123 ). The parameter group also displays a list of faults and warnings that have
previously occurred.
Event word (parameters 04.40 … 04.72 )
Parameter 04.40 Event word 1 can be configured by the user to indicate the status of
16 selectable events (ie. faults, warnings or pure events). It is possible to specify an
auxiliary code for each event to filter out other auxiliary codes.
