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 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 1.7 Motor current , 1.10
Motor torque , 1.11 DC voltage , 1.24 Flux actual % , 6.1 Main control word , 6.11 Main
status word , 24.1 Used speed reference , 30.1 Limit word 1 , 30.2 Torque limit status
and 90.1 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
