Cause
No SD card.
SD card write-protected.
SD card unreadable.
Power fail saving is requested too
frequently. Because of the limited
saving interval, some of the requests
do not trigger the saving and power
fail data may be lost. This may be
caused by DC voltage oscillation.
The calculated parameter checksum
does not match any enabled reference
checksum.
An action has been defined for a
parameter checksum mismatch but
the feature has not been configured.
Too much data in parameter mapping
table created in Drive customizer.
Parameter value saturated eg. by the
scaling specified in parameter
mapping table (created in Drive
customizer).
The motor parameters are set
incorrectly.
The drive is not dimensioned correctly.
Slip frequency is too small.
Synchronous and nominal speeds
differ too much.
Nominal speed is higher than
synchronous speed with 1 pole pair.

What to do
Insert a compatible, writable SD
card into the SD CARD slot of the
BCU control unit.
Insert a compatible, writable SD
card into the SD CARD slot of the
BCU control unit.
Insert a compatible, writable SD
card into the SD CARD slot of the
BCU control unit.
Check the supply voltage.
Check that all necessary approved
(reference) checksums (96.56...96.59)
are enabled in 96.55 Checksum control
word.
Check the parameter configuration.
Using 96.55 Checksum control
enable a checksum parameter and
copy the actual checksum into that
parameter.
Contact your local ABB representative
for configuring the feature, or disable
the feature in 96.54 Checksum
See the Drive customizer PC tool user's
manual (3AUA0000104167 [English]).
Check parameter scaling and format
in parameter mapping table. See the
Drive customizer PC tool user's manual
(3AUA0000104167 [English]).
Check the auxiliary code. See actions
for each code below.
Check the settings of the motor
configuration parameters in groups
98 and 99.
Check that the drive is sized
correctly for the motor.
