F0310
Short circuit on the transformer 1
secondary
Power-on.
Manual (
O
/RESET key).
Auto-reset.
DIx.
Networks.
Short circuit on the cables of the input trans-
former secondaries.
Short circuit on the coils of the input transformer
secondaries.
Defect on the transformer current measurement
circuit.
Defect on the input voltage measurement circuit.
Incorrect setting of the input transformer param-
eters.
A0315
Ground fault for neutral shift
Automatically eliminated when the volt-
age between the motor virtual neutral
point and the ground presents a value
below 20
Fault in the insultation to the ground of the con-
necting cables or of the load driven by the in-
verter.
Voltage between the virtual neutral of the mo-
tor and the ground of the system (P1144) above
25 % the voltage value of the motor phase.
Only detected with the load running.
F0316
Ground fault for neutral shift
Power-on.
Manual (
O
/RESET key).
Auto-reset.
DIx.
Networks.
Fault in the insultation to the ground of the con-
necting cables or of the load driven by the in-
verter.
Voltage between the virtual neutral of the mo-
tor and the ground of the system (P1144) above
50 % the voltage value of the motor phase for
more than 0.5 s.
Only detected with the load running.
F0317
Ground fault for current leak
Power-on.
Manual (
O
/RESET key).
Auto-reset.
DIx.
Networks.
Fault in the insultation to the ground of the con-
necting cables or of the load driven by the inverter
with the presence of current leak.
The sum of the three output currents is above
12.5 % of the inverter rated current.
Sensors measuring the output current are defec-
tive.
F0320
Vab measurement feedback fault
Contact WEG Service Center. Fault on the feedback circuit of the line voltage
between phases A and B at the inverter input.
Fiber optic Vab not connected, inverted or defec-
tive.
F0321
Vbc measurement feedback fault
Contact WEG Service Center. Fault on the feedback circuit of the line voltage
between phases A and B at the inverter input.
Fiber optic Vbc not connected, inverted or defec-
tive.
F0323
Ib_1 measurement feedback fault
Contact WEG Service Center. Fault on the feedback circuit of the current of
phase B at the inverter input.
Fiber optic Ib_x not connected, inverted or de-
fective.
Refer to the parameter P1893 description.
F0324
Ic_1 measurement feedback fault
Contact WEG Service Center. Fault on the feedback circuit of the current of
phase C at the inverter input.
Fiber optic Ic_x not connected, inverted or de-
fective.
Refer to the parameter P1893 description.
F0325
Vuv measurement feedback fault
Contact WEG Service Center. Fault on the feedback circuit of the line voltage
measured between phases U and V at the in-
verter output.
Fiber optic Vuv not connected, inverted or defec-
tive.
F0326
Vvw measurement feedback fault
Contact WEG Service Center. Fault on the feedback circuit of the line voltage
measured between phases U and V at the in-
verter output.
Fiber optic Vvw not connected, inverted or de-
fective.
