Fault tracing 395
A5EF
PU state feedback
State feedback from output
phases does not match control
signals.
Contact your local ABB representative.
A5F0
Charging feedback
Charging feedback signal
missing.
Check the feedback signal coming from
the charging system.
A686
Checksum mismatch
Programmable warning:
96.54
Checksum action
The calculated parameter
checksum does not match any
enabled reference checksum.
Check that all necessary approved
(reference) checksums (
96.71
…
96.72
)
are enabled in
96.55
Checksum control
word
.
Check the parameter configuration.
Using
96.55
Checksum control word
,
enable a checksum parameter and copy
the actual checksum into that parameter.
A687
Checksum
configuration
An action has been defined for
a parameter checksum
mismatch but the feature has
not been configured.
Contact your local ABB representative for
configuring the feature, or disable the
feature in
96.54
Checksum action
.
A6A4
Motor nominal value
The motor parameters are set
incorrectly.
Check the settings of the motor
configuration parameters in group 99.
The drive is not dimensioned
correctly.
Check that the drive is sized correctly for
the motor.
A6A5
No motor data
Parameters in group 99 have
not been set.
Check that all the required parameters in
group 99 have been set.
Note:
It is normal for this warning to
appear during the start-up and continue
until the motor data is entered.
A6A6
Voltage category
unselected
The voltage category has not
been defined.
Set voltage category in parameter
95.01
Supply voltage
.
A6B0
User lock is open
The user lock is open, ie. user
lock configuration parameters
96.100
…
96.102
are visible.
Close the user lock by entering an invalid
pass code in parameter
96.02
Pass
code
. See section
User lock
(page
109
).
A6D1
FBA A parameter
conflict
The drive does not have a
functionality requested by a
PLC, or requested functionality
has not been activated.
Check PLC programming.
Check settings of parameter groups
50
Fieldbus adapter (FBA)
.
A6E5
AI parametrization
The current/voltage hardware
setting of an analog input does
not correspond to parameter
settings.
Check the event log for an auxiliary code.
The code identifies the analog input
whose settings are in conflict.
Adjust parameter
12.15
/
12.25
.
Note:
Control board reboot (either by
cycling the power or through parameter
96.08
Control board boot
) is required to
validate any changes in the hardware
settings.
A6E6
ULC configuration
User load curve configuration
error.
Check the auxiliary code. See actions for
each code below.
0000 Speed points inconsistent.
Check that each speed point (parameters
37.11
…
37.15
) has a higher value than
the previous point.
0001 Frequency points inconsistent. Check that each frequency point
(
37.16
…
37.20
) has a higher value than
the previous point.
