Fault type
Output phase
Possible cause
 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
 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
 SI external fault input

Fault tracking
What to do
 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
 Check input power
 Check installation
distribution
 Check the output
distribution
 Check the motor and
cable
 Clean the air duct or
the fan
 Reduce the ambient
temperature
 Check the external
device input
