Code Warning
(hex)
AE79 Power fail saving
AE7F User pass code not
changed
AE85 Charging count
AE87 Ext earth leakage
AE88 Parameter map
configuration
AE89 Mapped parameter
value cut
AE8A User lock is open
AE8B User pass code not
confirmed
AE8C Control unit battery
AEA0 Phase order
Cause
Power fail saving is
requested too frequently.
Due to 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.
User pass code has not been
changed.
There are too many DC link
charging attempts.
External earth fault triggered
by input selected with
parameter 131.28 Ext earth
leakage signal source.
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 user lock is open, ie. user
lock configuration
parameters 196.100...196.102
are visible.
A new user pass code has
been entered in parameter
196.100 but not confirmed in
196.101.
The battery of the control
unit is low.
Supply unit has detected that
phase order differs from
expected.
What to do
Check the supply voltage.
For improved cybersecurity, it is highly
recommended that you set a user pass
code to prevent, for example, the
changing of parameter values and/or
the loading of firmware and other files.
Refer to section User lock
for instructions on changing the pass
code.
Two attempts in five minutes is
allowed to prevent charging circuit
overheating.
Check external earth fault source.
Usually only one device is allowed in
the same network.
Check AC fuses.
Check for earth leakages.
Check supply cabling.
Check power modules.
Check there are no power factor
correction capacitors or surge
absorbers in supply cable.
If no earth fault can be detected,
contact your local ABB representative.
See Drive customizer PC tool user's
manual (3AUA0000104167 [English]).
Check parameter scaling and format in
parameter mapping table. See Drive
customizer PC tool user's manual
(3AUA0000104167 [English]).
Close the user lock by entering an
invalid pass code in parameter
Pass code. See section
37).
Confirm the new pass code by
entering the same code in 196.101. To
cancel, close the user lock without
confirming the new code. See section
User lock (page 37).
Replace control unit battery.
This warning can be suppressed by
using parameter 131.40.
Make sure that all direct-on-line fans in
power units are rotating in correct
direction.
This warning can be suppressed by
using parameter 131.40.
