A5EE Measurement circuit DFF Measurement circuit fault. Contact your local ABB
representative.
A5EF PU state feedback State feedback from output
phases not matching with
control signals.
Contact your local ABB
representative.
A5F0 Charging feedback Charging feedback signal
missing.
Check the feedback signal coming
from the charging system.
A5F1 Redundant measurement Duplicated measurements are
beyond limits.
Contact your local ABB
representative.
A5F2 Overtemperature hw Excessive hardware
temperature.
Contact your local ABB
representative.
A682 Flash erase speed Flash erase speed exceeded. Avoid forcing unnecessary
parameter saves by parameter
96.07 Parameter save manually or
cyclic parameter writes (such as
user logger triggering through
parameters).
Check the auxiliary code (format
XYYYYZZZ). “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. The drive is not
dimensioned correctly.
Check the settings of motor
configuration in parameter groups
98 and 99 and check if drive is sized
correctly for the motor.
A6A5 No motor data Parameters in group 99 are not
set.
Set the required parameters in
group 99.
A6A6 Voltage category unselected Voltage category is not defined. Set voltage category in parameter
95.01 Supply voltage.
A7AC I/O Module internal error Calibration data is not stored in
the I/O module. Analog signals
are not working with full
accuracy.
Replace I/O module.
AFF8 Motor heating active Pre-heating is being performed Informative warning. Motor pre-
heating is active. Current specified
by parameter 21.16 Pre-heating
time delay is being passed through
the motor.
A6A7 System time not set System time is not set.
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.
A6B1 User pass code not confirmed New pass code is entered in
parameter 96.100 and not
confirmed in 96.101.
Confirm the new pass code by
entering the same code in 96.101.
A6D1 FBA A parameter conflict PLC requested functionality is
not activated.
Check PLC programming.
Code
(hex)
Warning/Aux code (aux code
visible only on assistant control
panel and drive composer)
Cause What to do
1 – Slip frequency is too small 5 – Nominal voltage is outside limits
2 – Synchronous and nominal speeds differ
too much
6 – Nominal power is higher than
apparent power.
3 – Nominal speed is higher than
synchronous speed with 1 pole pair
7 – Nominal power not consistent with
nominal speed and torque
4 – Nominal current is outside limits
