Cause

The acceleration is too fast

Reset the rotating motor

The voltage of the power
supply is too low.

The load is too heavy.

Close loop vector control,
reverse direction of the
code panel and long
low-speed operation

Phase loss or fluctuation of
input R, S, T

U, V, W phase loss input (or
serious asymmetrical three
phase of the load)

Air duct jam or fan damage

Ambient temperature is too
high.

The time of overload
running is too long.

SI external fault input
terminals action

The baud rate setting is
incorrect.

Fault occurs to the
communication wiring.

The communication
address is wrong.

There is strong interference
to the communication.

The connection of the
control board is not good

Assistant power is bad

Hall components is broken

The modifying circuit is
abnormal.

Solution

Increase the ACC time

Avoid the restarting after
stopping.

Check the power of the supply
line

Select a VFD with bigger power.

Select a proper motor.

Check input power

Check installation distribution

Check the output distribution

Check the motor and cable

Refer to the overcurrent solution

Redistribute dredge the wind
channel or change the fan

Low the ambient temperature

Check and reconnect

Change the power

Change the power unit

Change the main control panel

Check the external device input

Set proper baud rate

Check the communication
connection distribution

Set proper communication
address.

Chang or replace the connection
distribution or improve the
anti-interference capability.

Check the connector and re-plug

Change the hall

Change the main control panel
