Cause
wires is not good
Short-to-ground occurs.
The input voltage is abnormal
There is large
feedback
No braking components
Braking energy is not open
The acceleration
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
circuited or the output is phase
loss
There is strong
interference
The overvoltage
protection is not open
The voltage of the grid is too
low
overvoltage
The
protection is not open
The voltage of the grid is too
low
The rated current of the motor
is not correctly set
The motor stall
transients is too strong
The acceleration is too fast

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
energy
it needs to increase the energy
consumption components
Install
components
Check the setting of related
function codes
or
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
is short not smooth
Check the output configuration.
Check
external interference
Check the setting of related
stall function codes
Check the input power of the grid
Check the setting of related
stall
function codes
Check the power of the grid
Reset the rated current of the
motor
Check the load and adjust the
or load
torque lift
Increase the ACC time
Fault tracking
Solution
the dynamic braking
if there is strong
