ault code
Fault type Possible cause What to do
OUt1 IGBT Ph-U fault
 The acceleration is too
fast
 IGBT module fault
 Misaction caused by
interference
 The connection of the
driving wires is not good,
 Grounding is not properly
 Increase Acc time
 Change the power unit
 Check the driving wires
 Inspect external
equipment and eliminate
interference
OUt2 IGBT Ph-V fault
OUt3 IGBT Ph-W fault
OC1
Over-current when
acceleration
 The acceleration or
deceleration is too fast
 The voltage of the grid is
too low
 The power of the inverter
is too low
 The load transients or is
abnormal
 The grounding is short
circuited or the output is
phase loss
 There is strong external
interference
 The overvoltage stall
protection is not open
 Increase the ACC time
 Check the input power
 Select the inverter with a
larger power
 Check if the load is short
circuited (the grounding
short circuited or the wire
short circuited) or the
rotation is not smooth
 Check the output
configuration.
 Check if there is strong
interference
 Check the setting of
relative function codes
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
 No braking components
 Braking energy is not open
 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 add the dynamic
braking components
 Install the braking
components
 Check the setting of
relative function codes
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
 The overvoltage stall
protection is not open
 Check the input power of
the supply line
 Check the setting of
relative function codes
