Check the Light Emitting Diodes visible through a
hole in the inside isolation cover (see
) follow table below.

Serial communication problems If the bus address is set for
a high value, communication may seem to be impossible,
if the high address is not scanned by the master. The
address is not changed back to factory setting with reset
to factory setting function.
4.2.3 Warnings
The display flashes between normal state and warning. A
warning comes up on the first and second line of the
display. See example

WARNING/ALARM 2
Live zero fault (LIVE ZERO ERROR):
The current signal on terminal 1 is less than 50% of the
value set in parameter 336
Terminal 1, min. scaling
.
WARNING/ALARM 4
Phase loss (MAINS PHASE LOSS):
Phase missing on the supply side. Check the supply
voltage to the FC motor.
WARNING 5
Voltage warning high (DC LINK VOLTAGE HIGH):
The intermediate circuit voltage (DC) is higher than the
overvoltage limit of the control System, see
. The
FC motor 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, see
. The
FC motor is still active.
ALARM 7
Overvoltage (DC LINK OVERVOLT):
If the intermediate circuit voltage (DC) exceeds the inverter
overvoltage limit (see
), the FC motor will trip.
Furthermore, the voltage will be stated in the display.
ALARM 8
Undervoltage (DC LINK UNDERVOLT):
If the intermediate circuit voltage (DC) drops below the
inverter lower voltage limit (see
), the FC motor
will trip after 3-28 s, depending on unit. Furthermore, the
voltage will be stated in the display. Check whether the
supply voltage matches the FC motor, see
.
WARNING/ALARM 9
Inverter overload (INVERTER TIME):
The electronic, thermal inverter protection reports that the
FC motor is about to cut out because of an overload (too
high current for too long). The counter for electronic,
thermal inverter protection gives a warning at 95% and
trips at 100%, while giving an alarm. The FC motor cannot
be reset until the counter is below 90%.
