Goodrive200 inverters Fault tracking
201
Fault 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
