Fault code Fault type Possible cause What to do
OC2
Over-current when
deceleration

The voltage of the grid is
too low

The pow 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

Select t 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
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
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
OL1 Motor overload

The voltage of the power
supply is too low

The motor setting rated
current is incorrect

The motor stall or load
transients is too strong

Check the power of the
supply line

Reset the rated current of
the motor

Check the load and adjust
the torque lift
OL2 VFD overload

The acceleration is too fast

Reset the rotating motor

The voltage of the power
supply is too low

The load is too heavy

The motor power is too
small

Increase the ACC time

Avoid the restarting after
stopping

Check the power of the
supply line
