Fault code Fault type Possible cause What to do
OL1 Motor overload
 The voltage of the power
supply is too low

The motor setting rated
current is incorrect

The motor stall or load
transients is too strong
 Check the power of the
supply line

Reset the rated current of
the motor

Check the load and adjust
the torque lift
OL2 Inverter overload

The acceleration is too
fast

Reset the rotating motor

The voltage of the power
supply is too low
 The load is too heavy

The motor power is too
small

Increase the ACC time

Avoid the restarting after
stopping

Check the power of the
supply line
 Select an inverter with
bigger power
 Select a proper motor
OL3 Electrical overload

The inverter 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
