OV1
Accelerating
overvoltage
1. The input voltage is
abnormal.
2. There is large energy
feedback.
3. No braking components.
4. Braking energy is not
open
1. Check the input power
2. 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.
3. Install the braking
components.
4. Check the setting of
relative function codes.

OV3
Constant
overvoltage
OC1
Accelerating
overcurrent
1. The acceleration or
deceleration is too fast.
2. The voltage of the grid is
too low.
3. The power of the inverter
is too low.
4. The load transients or is
abnormal.
5. The grounding is short
circuited or the output is
phase loss.
6. There is strong external
interference.
7. The overvoltage stall
protection is not open.
1. Increase the ACC time
2. Check the input power
3. Select the inverter with a
larger power
4. Check if the load is short
circuited (the grounding short
circuited or the wire short
circuited) or the rotation is not
smooth.
5. Check the output
configuration.
6. Check if there is strong
interference.
7. Check the setting of
relative function codes.
