overflow
Internal fault.
Reset the fault. Contact your local ABB
representative if the fault persists.

Internal fault.
Reset the fault. Contact your local ABB
representative if the fault persists.
7081
Control panel loss
Programmable fault:
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.
7082
I/O module comm loss Communication between IO
module and drive is not
working properly.
Replace the drive.
7086
I/O module AI Over
voltage
Overvoltage detected in AI. AI
is changed to voltage mode. AI
will return automatically back
to mA mode when the AI signal
level is in accepted limits.
Check AI signal levels.
7121
Motor stall
Programmable fault:
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.
7122
Motor overload
Motor current is too high.
Check the motor, and the machinery
coupled to motor, for overload.
Adjust the parameters used for the motor
overload function (
…
) and
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 minimum/maximum frequency
settings, parameters
Check adequacy of motor braking torque.
Check applicability of torque control.
Check need for brake chopper and
resistor(s).
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
Check used supply voltage and voltage
selection parameter
