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
capability
ItE
Current detection
fault
The connection of the
control board is not good
Hall components is broken
The modifying circuit is
abnormal
Check the connector and
re-plug
Change the hall
Change the main control
panel
tE
Autotuning fault
The motor capacity does
not comply with the VFD
capability
The rated parameter of the
motor does not set correctly.
The offset between the
Change the VFD model
Set the rated parameter
according to the motor
nameplate
Empty the motor load and
re-identify
