Fault type Possible cause What to do
OUt1 IGBT Ph-U fault
OUt2 IGBT Ph-V fault
OUt3 IGBT Ph-W fault
1. The acceleration is too
fast.
2. IGBT module fault.
3.The connection of the
driving wires is not good,
4. Grounding is not properly.
1. Increase Acc time.
2. Change the power unit.
3. Check the driving wires.
4. Inspect external
equipment and eliminate
interference.
OC1
Over-current when
acceleration
OC2
Over-current when
deceleration
OC3
Over-current when
constant speed
running
1. The acceleration or
deceleration is too fast.
2. The voltage of the grid is
too low.
3. The power of the inverter
is too low.
4. The load transients or is
abnormal.
5. The grounding is short
circuited or the output is
phase loss.
6. There is strong external
interference.
1. Increase the ACC time
2. Check the input power
3. Select the inverter with a
larger power
4. Check if the load is short
circuited (the grounding
short circuited or the wire
short circuited) or the
rotation is not smooth.
5. Check the output
configuration.
6. Check if there is strong
interference.
OV1
Over-voltage
when acceleration
OV2
Over-voltage
when deceleration
OV3
Over-voltage
when constant
speed running
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.
UV
DC bus
Under-voltage
The voltage of the power
supply is too low.
Check the input power of
the supply line
