13-4 Troubleshooting 3AXD50000011888
Table 13-1 Warning Messages (Alphabetical by Keypad Text)
Warning Fault # Cause What to do
Measurement circuit
DFF
A5EE Measurement circuit fault. Contact your local ABB representative.
PU state feedback A5EF State feedback from
output phases does not
match control signals.
Contact your local ABB representative.
Charging feedback A5F0 Charging feedback signal
missing.
Check the feedback signal coming from the charging
system.
Motor nominal value A6A4 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.
No motor data A6A5 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.
Supply voltage
unselected
A6A6 The supply voltage has
not been defined.
Set supply voltage in parameter 95.01 Supply voltage.
FBA A parameter
conflict
A6D1 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) and 51 FBA A settings.
FBA B parameter
conflict
A6D2 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) and 54 FBA B settings.
AI parametrization A6E5 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 either the hardware setting (on the drive control
unit) or 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.
Motor stall
Programmable warning:
31.24 Stall function
A780 Motor is operating in stall
region because of e.g.
excessive load or
insufficient motor power.
Check motor load and drive ratings.
Check fault function parameters.
Motor fan
Programmable warning:
35.106 DOL starter event type
A781 No feedback received
from external fan.
Check external fan (or other equipment controlled) by the
logic.
Check settings of parameters 35.100…35.106.
FEN temperature A782 Error in temperature
measurement when
temperature sensor (KTY
or PTC) connected to
encoder interface FEN-xx
is used.
Check that parameter 35.11 Temperature 1 source /
35.21 Temperature 2 source setting corresponds to actual
encoder interface installation.
Error in temperature
measurement when KTY
sensor connected to
encoder interface FEN-01
is used.
FEN-01 does not support temperature measurement with
KTY sensor. Use PTC sensor or other encoder interface
module.
Brake resistor A791 Brake resistor broken or
not connected.
Check that a brake resistor has been connected.
Check the condition of the brake resistor.
