Possible cause
What to do
abnormal.
5. The grounding is short
circuited or the output is
phase loss.
6. There is strong external
interference.
circuited) or the rotation is not
smooth.
5. Check the output
configuration.
6. Check if there is strong
interference.
OV1
Over-voltage when
acceleration
1. The input voltage is
abnormal.
2. There is large energy
feedback.
1. Check the input power
2. 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 components.
OV2
Over-voltage when
deceleration
OV3
Over-voltage when
constant speed
running
UV
DC bus
Under-voltage
The voltage of the power
supply is too low.
Check the input power of the
supply line
OL1
Motor overload
1. The voltage of the power
supply is too low.
2. The motor setting rated
current is incorrect.
3. The motor stall or load
transients is too strong.
1. Check the power of the
supply line
2. Reset the rated current of
the motor
3. Check the load and adjust
the torque lift
OL2
Inverter overload
1. The acceleration is too fast
2. Reset the rotating motor
3. The voltage of the power
supply is too low.
4. The load is too heavy.
5. Close loop vector control,
reverse direction of the code
panel and long low-speed
operation
1. Increase the ACC time
2. Avoid the restarting after
stopping.
3. Check the power of the
supply line
4. Select an inverter with
bigger power.
5. Select a proper motor.
OL3
Electrical overload
The inverter will report
overload pre-alarm according
to the set value.
Check the load and the
overload pre-alarm point.
