abnormal
The grounding is short
circuited or the output is
phase loss
There is strong external
interference
circuited) or the rotation is not
smooth
Check the output configuration.
Check if there is strong
interference
OV1
Accelerating
overvoltage
The input voltage is
abnormal
There is large energy
feedback
Check the input power
Check if the DEC time of the
load is too short or the inverter
starts during the rotation of the
motor or it needs to increase the
energy consumption

fault
The voltage of the power
supply is too low
Check the input power of the
supply line
OL1
Motor
overload
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
Check the power of the supply
line
Reset the rated current of the
motor
Check the load and adjust the
torque lift
OL2
Inverter
overload
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.
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.

Phase loss or fluctuation of
input R,S,T
Check input power
Check installation distribution
