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. s ca ling.
WARNING/ALARM 4: Mains phase fault
No phase on mains supply side. Check the supply
voltage to the frequency converter. This fault is only
activein3-phasemainssupply. Thealarmcanalso
occur w hen the load is pulsing. In this instance the
pulses must be dampened, e.g. using an inert ia 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
unchanged. If the UDC remains above the voltage
warning limit, the inverter will trip after a set tim e. 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 oc cur
when the connected 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 (U D C)
is lower than
Voltage warning low the frequency converter will give a
warning and the motor will continue to run unchanged.
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 frequen
cy converter is
switched off a brief warning 6 (and warning 8) appears.
WARNING/ALARM 7: Overvoltage
If the intermediate voltage (U DC) goes over the
inverter’s Over voltage lim
it the inverter will be switched
off until the U DC has once more fallen below the
overvoltage limit. If the UDC remains above the
overvoltag limit the inve
rter will trip after a set time.
The time depends on the device, and is set a t 5
- 10 sec. An overvoltage in the UDC can occur
