Fault tracing 07
A5EB PU board powerfail Power unit power supply
failure.
Contact your local ABB representative.
A5ED Measurement circuit
ADC
Measurement circuit fault. Contact your local ABB representative.
A5EE Measurement circuit
DFF
Measurement circuit fault. Contact your local ABB representative.
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.
A682 Flash erase speed
exceeded
The flash memory (in the
memory unit) has been erased
too frequently, compromising
the lifetime of the memory.
Avoid forcing unnecessary parameter
saves by parameter 96.07 or cyclic
parameter writes (such as user logger
triggering through parameters).
Check the auxiliary code (format XYYY
YZZZ). “X” specifies the source of
warning (1: generic flash erase
supervision). “ZZZ” specifies the flash
subsector number that generated the
warning.
A6A4 Motor nominal value The motor parameters are set
incorrectly.
Check the auxiliary code. See actions for
each code below.
The drive is not dimensioned
correctly.
0001 Slip frequency is too small. Check the settings of the motor
configuration parameters in groups 98
and 99.
Check that the drive is sized correctly for
the motor.
0002 Synchronous and nominal
speeds differ too much.
0003 Nominal speed is higher than
synchronous speed with 1 pole
pair.
0004 Nominal current is outside
limits
0005 Nominal voltage is outside
limits.
0006 Nominal power is higher than
apparent power.
0007 Nominal power not consistent
with nominal speed and
torque.
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.
