WARNING/ALARM 2: Live zero fault
The voltage or current signal on terminal 53 or 60 is
below 50% of the preset value in parameter 309 or 315
Terminal, min. scaling
.
WARNING/ALARM 4: Mains phase fault
No phase on mains supply side. Check the supply
voltage to the frequency converter. This fault is only
active in 3-phase mains supply. The alarm can also
occur when the load is pulsing. In this instance the
pulses must be dampened, e.g. using an inertia disc.
WARNING 5: Voltage warning high
If the intermediate circuit voltage (UDC) is higher than
Voltage warning high
the frequency converter will give
a warning and the motor will continue to run un-
changed. If the UDC remains above the voltage warn-
ing limit, the inverter will trip after a set time. The time
depends on the device, and is set at 5 - 10 sec. Note:
The frequency converter will trip with an alarm 7 (over-
voltage). A voltage warning can occur when the con-
nected mains voltage is too high. Check whether the
supply voltage is suitable for the frequency converter,
see
Technical data
. A voltage warning can also occur
if the motor frequency is reduced too quickly due to
ramp down time being too short.
WARNING 6: Voltage warning low
If the intermediate circuit voltage (UDC) is lower
than
Voltage warning low
the frequency converter will
give a warning and the motor will continue to run un-
changed. A voltage warning can occur when the con-
nected mains voltage is too low. Check whether the
supply voltage is suitable for the frequency converter,
see
Technical data
. When the frequency converter is
switched off a brief warning 6 (and warning 8) appears.
WARNING/ALARM 7: Overvoltage
If the intermediate voltage (UDC) goes over the inver-
ter's
Overvoltage limit
the inverter will be switched off
until the UDC has once more fallen below the over-
voltage limit. If the UDC remains above the overvoltag
limit the inverter will trip after a set time. The time de-
pends on the device, and is set at 5 - 10 sec. An
