Possible cause
according to the set value.
Hydraulic probe damage
Incorrect PV wiring
1. The acceleration
deceleration is too fast.
2. The VFD power is too low.
3. The load transients or is
abnormal.
4. The grounding is short
circuited.
1. The solar cell panel input
voltage is too high.
2. Model -4 is set as another
model.
1. The power of the solar cell
panel series is too low or it is
cloudy and rainy weather.
2. The motor start-up current
is too high.

Fault diagnosis and solution
Change the damaged hydraulic
probe.
Change the wiring direction of
the positive
terminals
cables again.
1. Increase the ACC or DCC
or
time.
2. Select the VFD with a larger
power.
3. Check if the load is short
circuited (the grounding short
circuited
circuited) or the rotation is not
smooth.
1. Reduce the number of solar
cell panels that are wired in
series.
2. Check and reset the model.
1. Increase the number of solar
cell panels or perform the test in
the normal sun light.
2. Change the motor.
Check the four communication
cables of 422 and ensure that
they are connected properly.
Adjust the boost PI parameters.
