wires is not good
Short-to-ground occurs.
OV1
Accelerating
overvoltage
The input voltage is abnormal
There is large energy
feedback
No braking components
Braking energy is not open
Check the input power
Check if the DEC time of the load
is too short or the VFD starts
during the rotation of the motor or
it needs to increase the energy
consumption components
Install the dynamic braking
components
Check the setting of related
function codes
OV2
Decelerating
overvoltage
OV3
Constant
overvoltage
OC1
Accelerating
overcurrent
The acceleration or
deceleration is too fast
The voltage of the grid is too
low
The power of the 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/DEC 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 related
function codes

fault
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 related
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
Increase the ACC time
