Code
Fault
Possible cause
Solution
protection
driving wires is not good
The grounding is not
good; Interference causes
maloperation
OV1
ACC overvoltage
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 increase the
energy consumption
components
Install the braking
components
Check the setting of relative
function codes
OV2
DEC overvoltage
OV3
Constant
overvoltage
OC1
ACC overcurrent
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
DEC overcurrent
OC3
Constant
overcurrent
UV
Bus undervoltage
fault
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
Motor rated current is
incorrect
The motor stall or load
Check the power of the
supply line
Reset the rated current of
the motor
Check the load and adjust
