Cause
Reset the rotating motor
The voltage of the grid is too
low.
The load is too heavy.
The motor power is too small
Phase loss or fluctuation of
input R,S,T
U,V,W phase loss input (or
serious asymmetrical
phase of the load)
Air duct jam or fan damage
Ambient temperature is too
high.
The time of overload running
is too long.
SI external fault
terminals action
The baud rate setting is
incorrect.
Fault occurs
communication wiring.
The communication address is
wrong.
There is strong interference to
the communication.
The connection of the control
board is not good
Hall components are broken
modifying
The
abnormal.
The motor capacity does not
comply with the VFD capability
The rated parameter of the
motor does not set correctly.
The offset between
191
Avoid the restarting after stopping.
Check the power of the grid
Select a VFD with bigger power.
Select a proper motor.
Check input power
Check installation distribution
Check the output distribution
