7081 Control panel loss
Programmable fault: 49.05
Communication loss
action
Control panel or PC tool
selected as active control
location for drive has ceased
communicating.
Check PC tool or control panel
connection.
Check control panel connector.
Disconnect and reconnect the control
panel.
7085 Incompatible option
module
Fieldbus option module not
supported.
Replace the module with a supported
type.
7100 Excitation current Excitation current feedback low
or missing
7121 Motor stall
Programmable fault: 31.24
Stall function
Motor is operating in stall
region because of e.g.
excessive load or insufficient
motor power.
Check motor load and drive ratings.
Check fault function parameters.
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.
73F0 Overfrequency Maximum allowed output
frequency exceeded.
Contact your local ABB
representative.
73B0 Emergency ramp
failed
Emergency stop did not finish
within expected time.
Check the settings of parameters
31.32 Emergency ramp supervision
and 31.33 Emergency ramp
supervision delay.
Check the predefined ramp times
(23.12…23.13 for mode Off1, 23.23
for mode Off3).
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.

underload curve.
See parameter 37.04 ULC underload
actions.
8002 ULC overload fault User load curve: Signal has
been too long over the
overload curve.
See parameter 37.03 ULC overload
actions.
