Poor grounding
fault
ACC is too fast.
The voltage of the grid is too low;
VFD power is too small
DEC is too fast
The load inertia torque is too large
VFD power is too small
Load transient or exception occurred
The voltage of the grid is too low

Solution
Increase ACC time
Ask for technical support
Check whether there is strong
interference surrounding
peripheral device.
Increase ACC time
Check the input power
Select the VFD with larger
power
Increase DEC time
Install dynamic
components
Select the VFD with larger
power
Check the load or reduce the
sudden change of load
Check the input power
Select the VFD with larger
in
power
Check the encoder and its
wiring
