Warnings and alarms
WARNING 1
Under 10 V (10 VOLT LOW)
The 10 V voltage from terminal 50 on the
control card is below 10 V.
Remove some of the load from terminal 50, as the 10
Volts supply is overloaded. Max. 17 mA/min. 590
.
WARNING/ALARM 2
Live zero fault (LIVE ZERO ERROR)
The current or voltage signal on terminal 53, 54 or
60 is below 50% of the value preset in parameter
309, 312 and 315
Terminal, min. scaling
.
WARNING/ALARM 4
Mains imbalance (MAINS IMBALANCE)
High imbalance or phase missing on the supply side.
Check the supply voltage to the AFD.
WARNING 5
Voltage warning high
(DC LINK VOLTAGE HIGH)
The intermediate circuit voltage (DC) is higher
than
Voltage warning high
, see table below. The
controls of the AFD are still enabled.
WARNING 6
Voltage warning low (DC LINK VOLTAGE LOW)
The intermediate circuit voltage (DC) is lower
than
Voltage warning low,
see table below. The
controls of the AFD are still enabled.
WARNING/ALARM 7
Overvoltage (DC LINK OVERVOLT)
If the intermediate circuit voltage (DC) is higher
than the Overvoltage limit of the inverter (see table
below), the AFD will trip after a fixed period. The
length of this period depends on the unit.

The voltages stated are the intermediate circuit
voltage of the AFD with a tolerance of ± 5 %.
The corresponding line voltage is the intermediate
circuit voltage divided by 1.35.
WARNING/ALARM 8
Undervoltage (DC LINK UNDERVOLT)
If the intermediate circuit voltage (DC) drops
below the
undervoltage limit
of the inverter, the
AFD will trip after a fixed period, the length of
the period depending on the unit.
Furthermore, the voltage will be stated in the
display. Check whether the supply voltage matches
the AFD, see
Technical data
