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

Rectifying
module
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
OH2
IGBT
overheated
EF
External fault
SI external fault input
terminals action
