code
Fault type
Possible cause
What to do
OUt3
IGBT Ph-W fault
interference
The connection of the
driving wires is not
good,
Grounding is not
properly
equipment and
eliminate interference
OC1
Over-current when
acceleration
The input voltage is
abnormal
There is large energy
feedback
Select the inverter with
a larger power
Check the input power
OC2
Over-current when
deceleration
OC3
Over-current when
constant speed running
OV1
Over-voltage when
acceleration
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
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
