7310
Overspeed
Motor is turning faster
than highest allowed
speed due to incorrectly
set minimum/maximum
speed, insufficient
braking torque or
changes in load when
using torque reference.
Check minimum/maximum
speed settings, parameters
and
Check adequacy of motor braking
torque.
Check applicability of torque
control.
Check need for brake chopper
and resistor(s).
73F0 Overfrequency
Maximum allowed output
frequency exceeded.
Check the auxiliary code.
00FA
Motor is turning faster
than the highest allowed
frequency due to
incorrectly set
minimum/maximum
frequency or the motor
rushes because of too
high supply voltage or
incorrect supply voltage
selection in parameter
.
Check minimum/maximum
frequency settings, parameters
and
.
Check used supply voltage and
voltage selection parameter
.

-
Contact your local ABB
representative, quoting the
auxiliary code.

FBA A
communication
Programmable fault:
Cyclical communication
between drive and
fieldbus adapter module
A or between PLC and
fieldbus adapter module
A is lost.
Check status of fieldbus
communication. See user
documentation of fieldbus
interface.
Check settings of parameter
groups
,
and
Check cable connections.
Check if communication master
is able to communicate.
8000 Unicos system
error
System fault.
Power cycle.
8009 Current limit
Motor actual current
exceeded the limit
defined in parameter
.
Reduce the motor load. Check for
any jam or stall in motor.
