too low.
3 ． The power of the inverter is
too low.
3. Select bigger capacity inverter.
OV1
Over-voltage when
acceleration
1. The input voltage is
abnormal
2. Restart the running motor
after sudden power loss.
1 Check the input power
2.Avoid restart-up after stopping
OV2
Over-voltage when
deceleration
1. Dec time is too short.
2.The inertia of the load is big.
3.The input voltage is
abnormal
1.Increase the Dec time
2. Increase the
energy-consuming components
3. Check the input power
OV3
Over-voltage when
constant speed
running
1. The input voltage changes
abnormally.
2. The inertia of the load is
big.
1. Install the input reactor
2.Add proper energy-consuming
components
UV
DC bus
Under-voltage
1. The voltage of the grid is
low
1.Check the input power supply of
the grid
OL1 Motor overload
1. The voltage of the power
supply is too low.
2. The motor setting rated
1. Check the power of the supply
line
2. Reset the rated current of the
