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 frequency converter.
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 frequency converter 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 frequency converter 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 frequency converter will trip after a fixed period.
The length of this period depends on the unit.
