OL2
[12] VFD
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 a VFD with bigger power.
Select a proper motor.
SPI
[13] Phase loss
on input side
Phase loss or fluctuation of
input R, S, T
Check input power
Check installation distribution
SPO
[14] Phase loss
on output side
U, V, W phase loss input (or
serious asymmetrical three
phase of the load)
Check the output distribution
Check the motor and cable

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

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.
Chang or replace the connection
distribution or improve the
anti-interference capability.
