The display flashes between normal state and warning.
A warning comes up on the first and second line
of the display. See examples below:

Alarm messages
The alarm comes up in the 2. and 3. line of
the display, see example below:
ALARM:12
SETUP
1
TRIP (RESET)
TORQUE LIMIT
WARNING 1
Under 10 Volts (10 VOLT LOW):
The 10 Volts voltage from terminal 50 on the
control card is below 10 Volts.
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 signal on terminal 60 is less than 50% of the
value set in parameter 315 Terminal 60,min. scaling.
WARNING/ALARM 3
No motor (NO MOTOR):
The motor check function (see parameter 122)
indicates that no motor has been connected to
the output of the frequency converter.
WARNING/ALARM 4
Phase fault (MAINS PHASE LOSS):
A phase is missing on the supply side or the
mains voltage imbalance is too high.
This mesage can also appear if there is a fault in the
input rectifier on the frequency converter.
Check the supply voltage and supply currents
to the frequency converter.
WARNING 5
Voltage warning high
(DC LINK VOLTAGE HIGH):
The intermediate circuit voltage (DC) is higher than
the overvoltage limit of the control system. The
frequency converter is still active.
WARNING 6
Voltage warning low (DC LINK VOLTAGE LOW):
The intermediate circuit voltage (DC) is below the
undervoltage limit of the control system. The
frequency converter is still active.
WARNING/ALARM 7
Overvoltag e (DC LINK OVERVOLT):
If the intermediate circuit voltage (DC) exceeds
the inverter overvoltage limit (see table), the
frequency converter will trip.
Furthermore, the voltage will be stated in the
display. The fault can be eliminated by connecting
a brake resistor (if the frequency converter
has an integral brake chopper, EB or SB). In
addition, Brake function/overvoltage c ontrol can
be activated in parameter 400.
