Goodrive100-PV Series Solar Pumping VFD Fault diagnosis and solution
59
7 Fault diagnosis and solution
Do as follows after the VFD encounters a fault:
1. Check to ensure there is nothing wrong with the keypad. If not, please contact with the local
office.
2. If there is nothing wrong, please check P07 and ensure the corresponding recorded fault
parameters to confirm the real state when the current fault occurs by all parameters.
3. See the following table for detailed solution and check the corresponding abnormal state.
4. Eliminate the fault and ask for relative help.
5. Check to eliminate the fault and carry out fault reset to run the VFD.

Solutions
OUt1
Inverter unit U
phase protection
1. The acceleration is too fast.
2. This phase IGBT is
damaged internally.
3. Interference causes
misoperation.
4. The drive wire is connected
improperly.
5. The load transients or is
abnormal.
6. The grounding is short
circuited.
1. Increase the acceleration
time.
2. Change the power unit.
3. Check the drive wire.
4. Check whether the peripheral
equipment has strong
interference sources.
OUt2
Inverter unit V
phase protection
OUt3
Inverter unit W
phase protection
OV1
ACC 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 VFD
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.
OV2
DEC overvoltage
OV3
Constant-speed
overvoltage
OC1
ACC overcurrent
1. The acceleration or
deceleration is too fast.
1. Increase the ACC time.
2. Check the input power.
