MAINS PHASE LOSS
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. Maximum load is 17 mA, minimum resistance is 590
Ω
.
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, Minimum
Scaling.
WARNING/ALARM 4
Mains Failure (MAINS PHASE LOSS)
Phase missing on the input power. Check the supply voltage to the
drive.
WARNING 5
Voltage Warning High
(DC LINK VOLTAGE HIGH)
The intermediate DC circuit voltage is higher than Voltage Warning
High, see table below. The drive is still controlling the motor.

Alarms
If an alarm is given, the present alarm number will be shown in line 2.
Lines 3 and 4 of the display will offer an explanation.
WARNING 6
Voltage Warning Low (DC LINK VOLTAGE LOW)
The intermediate DC circuit voltage is lower than Voltage Warning Low,
see table below. The drive is still controlling the motor.
WARNING/ALARM 7
Overvoltage (DC LINK OVERVOLT)
If the intermediate circuit voltage (DC) is higher than the Overvoltage
Limit of the drive (see table below), the drive will trip after a fixed
period. The length of this period depends upon the unit.
WARNING/ALARM 8
Undervoltage (DC LINK UNDERVOLT)
If the intermediate circuit voltage (DC) drops below the Undervoltage
Limit of the inverter, the drive will trip after a fixed period. The length of
the period depends upon the unit.
The voltage will be stated in the display. Check whether the supply
voltage matches the drive rating.
WARNING/ALARM 9
Inverter Overload (INVERTER TIME)
The electronic thermal inverter protection reports that the drive is about
to trip because of an overload. The counter for electronic thermal
inverter protection gives a warning at 98% and trips at 100% showing
an alarm. The drive cannot be reset until the counter drops below
90%.
