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.
 Close loop vector control,
reverse direction of the code
panel and long low-speed
operation
 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
Rectifying
module
overheated
OH2
IGBT
overheated

Air duct jam or fan damage
 Ambient temperature is too
high.

The time of overload running
is too long.

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
EF External fault

SI external fault input
terminals action
 Check the external device input
