GD200A series VFD Fault tracking
-114-
Fault code Fault type Possible cause What to do

The load is too heavy

The motor power is too
small
supply line

Select a VFD with bigger
power

Select a proper motor
OL3 Electrical overload

The VFD will report
overload pre-alarm according
to the set value

Check the load and the
overload pre-alarm point.
SPI Input phase loss

Phase loss or fluctuation of
input R,S,T

Check input power

Check installation
distribution
SPO Output phase loss

U,V,W phase loss input(or
serious asymmetrical three
phase of the load)

Check the output
distribution

Check the motor and cable
OH1 Rectify overheat

Air duct jam or fan damage

Ambient temperature is too
high

The time of overload
running is too long

Clean the air duct or the fan

Reduce the ambient
temperature
OH2 IGBT overheat
EF External fault

SI external fault input
terminals action

Check the external device
input
CE
Communication
error

The baud rate setting is
incorrect

Fault occurs to the
communication wiring.

The communication
address is wrong

There is strong interference
to the communication

Set proper baud rate

Check the communication
connection distribution

Set proper communication
address

Chang or replace the
connection distribution or
improve the anti-interference
