DIAGNOSTICS AND TROUBLESHOOTING
Fault/alarm Reset Possible causes
A0123
Programming alarm
It resets automatically after the cause is
eliminated. Alarm occurs when parameter P0169 is set to a
value beyond the one accepted by the overload
duty.
P0169 above 15 % of the value of P0295 (Inverter
rated current).
A0124
Parameter alteration with enabled
inverter
It resets automatically after the cause is
eliminated. Specific Fieldbus/Serial fault.
A0125
Reading/writing in inexistent
parameter
It resets automatically after the cause is
eliminated. Specific Fieldbus/Serial fault.
A0126
Parameter Value Out of Range
It resets automatically after the cause is
eliminated. Specific Fieldbus/Serial fault.
A0127
Function not configured for
Fieldbus
It resets automatically after the cause is
eliminated. Specific Fieldbus/Serial fault.
A0129
Fieldbus Connec. Inactive
It resets automatically after the cause is
eliminated. Specific Fieldbus/Serial fault.
A0130
Fieldbus Card Inactive
It resets automatically after the cause is
eliminated. Specific Fieldbus/Serial fault.
A0301
Input undervoltage
Eliminate automatically when the voltage
at the inverter input exceeds 75.5 %. Voltage on the input transformer secondary is be-
low 75.5 %.
Undervoltge on the supply line.
Wrong setting of the transformer primary taps.
A0302
Input overvoltage
Eliminate automatically when the voltage
at the inverter input is less than 113.5 %. Tensão na entrada do inversor superior a 114 %.
Overvoltage on the supply line.
Wrong setting of the transformer primary taps.

Power-on.
Manual (
O
/RESET key).
Auto-reset.
DIx.
Networks.
Phase loss on the supply line.
Voltage difference between the phases above
40 % of the rated value.
Voltage on any phase below 30 % of the rated
value.
F0309
Timeout in Ride-through state
Waiting Line
Power-on.
Manual (
O
/RESET key).
Auto-reset.
DIx.
Networks.
Time for the return of the power longer than the
time set at P0332 + P0333.
Inverter input voltage below 80 %.
Undervoltage in the mains supply.
Incorrect setting of the transformer primary taps;
