3. See the following table for detailed solution and check the corresponding abnormal state.
4. Eliminate the fault and ask for related help.
5. Check to eliminate the fault and carry out fault reset to run the VFD.
Fault code Fault type Possible cause Solutions
OUt1
Inverter unit U
phase protection

The acceleration is too
fast;

IGBT module fault;

Misacts caused by
interference;

The connection of the
driving wires is not good;

Grounding is not
properly.

Increase ACC time;

Change the power unit;

Check the driving wires;

Inspect external
equipment and eliminate
interference.
OUt2
Inverter unit V
phase protection
OUt3
Inverter unit W phase
protection
OV1
Overvoltage during
acceleration

The input voltage is
abnormal;

There is large energy
feedback;

No braking components;

Braking energy is not
open.

Check the input power;

Check if the DEC time of
the load is too short or
the VFD starts during the
rotation of the motor or it
needs to increase the
energy consumption
components;

Install the braking
components;

Check the setting of
related function codes.
OV2
Overvoltage during
deceleration
OV3
Overvoltage during
constant speed
running
OC1
Overcurrent during
acceleration

The acceleration or
deceleration is too fast;

The voltage of the grid is
too low;

The power of the VFD is
too low;

The load transients or is
abnormal;

The grounding is short
circuited or the output is
phase loss;

There is strong external
interference;

The overvoltage stall

Increase the ACC time;

Check the input power;

Select the VFD with a
larger power;

Check if the load is short
circuited (the grounding
short circuited or the wire
short circuited) or the
rotation is not smooth;

Check the output
configuration;

Check if there is strong
interference;

Check the setting of
OC2
Overcurrent during
deceleration
OC3
Overcurrent during
constant speed
running
