Code
Fault
Possible cause
Solution
transients is too strong
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.
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
Air duct jam or fan
damage
Ambient temperature is
too high.
The time of overload
running is too long.
Redistribute dredge the
wind channel or change the
fan
Low the ambient
temperature
OH2
IGBT overheated
EF
External fault
SI external fault input
terminals action
Check the external device

485 communication
fault
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.
Change or replace the
connection distribution or
improve the
anti-interference capability.
ItE
Current-detecting
fault
The connection of the
control board is not good
Hoare component is
Check the connector and
repatch
Change the Hoare
