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

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.

Current-detecting
fault
The connection of the
control board is not good
Hoare component is
Check the connector and
repatch
