Cause
High temperature difference between
the IGBTs of different phases. The
amount of available temperatures
depends on the frame size.
Overtemperature detected either in
cabinet, LCL filter or auxiliary
transformer.
An auxiliary cooling fan is stuck or
disconnected.
The hardware of the supply unit does
not match the information stored in
the memory unit. This may occur eg,
after a firmware update or memory
unit replacement.
Control program does not receive
main contactor on (1)
acknowledgement through digital
input even control program has closed
the contactor control circuit with relay
output.
Main contactor / main breaker is not
functioning properly, or there is a
loose / bad connection.
Synchronization to supply network has
failed.
Rating ID load error.
There are two types of licenses being
used in ACS880 drives:
licenses that need to be found from
the unit which allow the firmware to
be executed, and licenses that prevent
the firmware from running. The license
is indicated by the value of the
auxiliary code field. The license is
Nxxxx, where xxxx is indicated by the
4-digit value of the auxiliary code field.
8201: A restrictive license is found
from the unit. The firmware on this
inverter unit cannot be executed
because a Low harmonic license is
found from the unit. This unit is meant
to be used with IGBT supply control
program (2Q) only.
Control panel or PC tool selected as
active control location has ceased
communicating.
What to do
See AE15 Excess temperature
difference.
Check the cooling of the cabinet, LCL
filter and auxiliary transformer.
Check the fan operation and
connection.
Replace the fan if faulty.
Cycle the power to the supply unit. If
the control unit is externally powered,
reboot the control unit (using
parameter 96.108 LSU control board
boot) or by cycling its power.
If the problem persists, contact your
local ABB representative.
Check main contactor / main breaker
control circuit wiring.
Check the status of other switches
connected to contactor control circuit.
See the delivery-specific circuit
diagrams.
Check main contactor operating
voltage level (should be 230 V).
Check digital input DI3 connections.
Monitor possible network transients.
Contact your local ABB representative.
Check the line-converter control
program. Record the auxiliary codes
of all active licensing faults and
contact your product vendor for
further instructions.
This fault requires a reboot of the
control unit either by switching the
power off and on, or using parameter
96.108 LSU control board
8201: Contact your product vendor for
further instructions.
Check PC tool or control panel
connection.
Check control panel connector.
Replace control panel in mounting
platform.
