Fault tracing 543
4E06 Cabinet or LCL
overtemperature
Overtemperature detected
either in cabinet, LCL filter or
auxiliary transformer.
Check the cooling of the cabinet, LCL
filter and auxiliary transformer.
5E05 Rating ID mismatch 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.
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.
5E06 Main contactor Fault 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.
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.
6E19 Synchronization fault Synchronization to supply
network has failed.
Monitor possible network transients.
6E1A Rating ID fault Rating ID load error. Contact your local ABB representative.
6E1F Licensing fault 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.
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 boot.
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.
Contact your product vendor for further
instructions.
7E01 Panel loss Control panel or PC tool
selected as active control
location has ceased
communicating.
Check PC tool or control panel
connection.
Check control panel connector.
Replace control panel in mounting
platform.
8E07 Net lost Net lost is detected. Duration
of net lost is too long.
Resynchronize the IGBT supply unit to
the grid after net lost.
