Cause
 The acceleration or deceleration
is too fast
 The voltage of the grid is too low
 The power of inverter is too low
 The load transients or is
abnormal
 The grounding is short circuited
or the output is phase loss
 There is strong external
interference
 The overvoltage stall protection
is not open
 The voltage of the power supply
is too low
 The overvoltage stall protection
is not open
 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.
 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.
to increase the energy consumption
components
 Install the brake components
 Check the setting of relative function
codes
 Increase the ACC time
 Check the input power
 Select the inverter with a larger
power
 Check if the load is short circuited
(the grounding short circuited or the
wire short circuited) or the rotation is
not smooth
 Check the output configuration.
 Check if there is strong interference
 Check the setting of relative function
codes
 Check the input power of the supply
line
 Check the setting of relative function
codes
 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 input power
 Check installation distribution
 Check the output distribution
 Check the motor and cable
 Refer to the overcurrent solution
 Redistribute dredge the wind
