Fault Description
Possible Reasons
Solutions
Fu.01
Over current occurs
in inverter
acceleration running
process
1. The acceleration time is
too short.
2. Start the rotating motor
directly.
3. The torque boost is preset
as too large.
4. The network voltage is
too low.
1. Extend acceleration time.
2. Restart the motor after stop
3. Reduce voltage of torque
boost.
4. Check the network voltage
and reduce power.
Fu.02
Over current occurs
in inverter
deceleration
running process
The acceleration time is too
short.
Increase the acceleration time
Fu.03
Over current occurs
in inverter running
or stop condition
1. Load changes suddenly
2. The network voltage is
too low.
1. Reduce the load fluctuation.
2. Check the power voltage.
Fu.04
Overvoltage occurs
in inverter
acceleration
running process
1. The input voltage is too
high.
2. Put the power on and
off frequently.
1. Check the power.
2. Lower the setting of
acceleration torque level.
Fu.05
Overvoltage occurs
in inverter
deceleration
running process
1. The acceleration time is
too short.
2. The input voltage is
abnormal.
1. Extend the acceleration time.
2. Check the power voltage.
3. Install braking resistor or
reselect braking resistor.
Fu.06
Overvoltage occurs
in inverter running
process
1. The power voltage is
abnormal.
2. There is energy feedback
load.
1. Check the power voltage.
2. Install the braking unit and
braking resistor or reselect
braking resistor.
Fu.07
Overvoltage occurs
in inverter stop
condition
The power voltage is
abnormal.
Check the power voltage.
Fu.08
Under-voltage
occurs in inverter
running process
1. The power voltage is
abnormal.
2. There is starting operation
of heavy load in network.
1. Check the power voltage.
2. Supply power separately.
Fu.09
~Fu.10
Reserve
Fu.11
Electromagnetic
interference
Jamming drive signal
1. Check whether the wiring is
reasonable.
2. The strong and weak lines
are separated.
Fu.12
Inverter overload
1. The load is too large.
2. The acceleration time is
too short.
3.The torque boost is too
high.
4. The network voltage is
too low.
1. Reduce load or change a
larger capacity inverter.
2. Extend the acceleration time.
3. Reduce the voltage of
torque boost.
4. Check the network voltage.
Fu.13
Motor overload
1. The load is too large.
2. The acceleration time is
1. Reduce load.
2. Extend the acceleration time.
