according to the set value.
tSF
Hydraulic probe
damage
Hydraulic probe damage
Change the damaged hydraulic
probe.
PINV
PV reverse
connection fault
Incorrect PV wiring
Change the wiring direction of
the positive and negative
terminals and connect the
cables again.
PVOC
PV overcurrent
1. The acceleration or
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. Increase the ACC or DCC
time.
2. Select the VFD with a larger
power.
3. Check if the load is short
circuited (the grounding short
circuited or the wire short
circuited) or the rotation is not
smooth.
PVOV
PV overvoltage
1. The solar cell panel input
voltage is too high.
2. Model -4 is set as another
model.
1. Reduce the number of solar
cell panels that are wired in
series.
2. Check and reset the model.
PVLV
PV undervoltage
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.
1. Increase the number of solar
cell panels or perform the test in
the normal sun light.
2. Change the motor.
E-422
Fault on
communication with
boost module 422
Improper contact with the
communication cables
Check the four communication
cables of 422 and ensure that
they are connected properly.
OV
Bus overvoltage
detected at the
boost module side
The sun light changes
suddenly.
Adjust the boost PI parameters.
Enlarge the values of P19.07
and P19.08.
A-LS
Weak light alarm
The sun light is weak or the
solar cell panel configuration
The equipment automatically
runs when the light becomes
