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
running
protection is not open
The input voltage is
abnormal
There is large energy
feedback
No braking components
Braking energy is not open
running
The voltage of the power
DC bus supply is too low
The overvoltage stall
protection is not open
The voltage of the power
supply is too low
The motor setting rated
current is incorrect
The motor stall or load
transients is too strong
The acceleration is too fast
Reset the rotating motor
The voltage of the power
supply is too low

What to do
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 codes
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 add
the dynamic braking
components
Install the braking
components
Check the setting of relative
function codes
Check the input power of
the supply line
Check the setting of relative
function codes
Check the power of the
supply line
Reset the rated current of
the motor
Check the load and adjust
the torque lift
Increase the ACC time
Avoid the restarting after
stopping
Check the power of the
