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.
The load is too heavy.
The motor power is too
small.
The inverter will report
overload pre-alarm
according to the set value.
Phase loss or fluctuation of
input R,S,T
U,V,W phase loss input(or
serious asymmetrical three
phase of the load)
Air duct jam or fan damage
Ambient temperature is too
high.
The time of overload running
is too long.

Fault tracking
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 supply
line
Select an inverter with bigger
power.
Select a proper motor.
Check the load and the overload
pre-alarm point.
Check input power
Check installation distribution
Check the output distribution
Check the motor and cable
Refer to the overcurrent solution
Redistribute dredge the wind
channel or change the fan
Low the ambient temperature
Check and reconnect
Change the power
Change the power unit
Change the main control panel
Check the external device input
