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 30.11 Minimum
speed and 30.12 Maximum speed.
Check adequacy of motor braking torque.
Check applicability of torque control.
Check need for brake chopper and
resistor(s).
73B0 Emergency ramp
failed
Emergency stop did not finish
within expected time.
Check the predefined ramp times
(23.11…23.15, 23.12…23.13 for mode
Off1, 23.23 for mode Off3).
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 95.01
Supply voltage.
Check minimum/maximum frequency
settings, parameters 30.13 Minimum
frequency and 30.14 Maximum
frequency.
Check used supply voltage and voltage
selection parameter 95.01 Supply
voltage.
Other - Contact your local ABB representative,
quoting the auxiliary code.
7510 FBA A communication
Programmable fault: 50.02
FBA A comm loss func
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 50
Fieldbus adapter (FBA), 51 FBA A
settings, 52 FBA A data in and 53 FBA A
data out.
Check cable connections.
Check if communication master is able to
communicate.
8000 Unicos system error System fault. Power cycle.
8001 ULC underload fault User load curve: Signal has
been too long under the
underload curve.
See parameter 37.04 ULC underload
actions.
001 Underload occurred between
speed point 37.11 ULC speed
table point 1 and 37.12 ULC
speed table point 2.
Check the load.
002 Underload occurred between
speed point 37.12 ULC speed
table point 2 and 37.13 ULC
speed table point 3.
Check the load.
003 Underload occurred between
speed point 37.13 ULC speed
table point 3 and 37.14 ULC
speed table point 4.
Check the load.
