Code
Fault
Cause
Solution
OV1
ACC overvoltage
The input voltage is abnormal
There is large energy feedback
No brake components
Brake energy is not open
Check the input power
Check if the DEC time of the load is
too short, or the motor is started
when it is rotating.
Install a dynamic brake components
Check the setting of relative function
codes
OV2
DEC overvoltage
OV3
Constant-speed
overvoltage
OC1
ACC overcurrent
The acceleration or deceleration
is too fast
The voltage of the grid is too low
The power of VFD is too low
The load transients or is
abnormal
The grounding is short circuited
or the output is phase loss
There is strong external
interference
The overvoltage stall protection
is not open
Increase the ACC time
Check the input power
Select the VFD with a larger power
Check if the load is short circuited
(the grounding short circuited or the
wire short circuited) or the rotation is
not smooth
Check the output configuration.
Check if there is strong interference
Check the setting of relative function

overcurrent
UV
Bus undervoltage
The voltage of the grid is too low
The overvoltage stall protection
is not open
Check the input power of the grid;
Check the setting of relative function
codes
OL1
Motor overload
The voltage of the grid is too low
The rated current of the motor is
not correctly set
The motor stall or load transients
is too strong
Check the power of the grid
Reset the rated current of the motor
Check the load and adjust the torque
lift
OL2
VFD overload
The acceleration is too fast
Restart the rotating motor
The voltage of the grid 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 grid
Select a VFD with bigger power.
Select a proper motor.
SPI
Input side phase
loss
Phase loss or fluctuation of input
R,S,T
Check input power
Check installation distribution
SPO
Output side 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.
Dredge the vent duct or replace the
fan
