Warnings
A warning will flash in line 2, while an explanation is given in line 1.
WARNING 1
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 ERROR
The current or voltage signal on terminal 53, 54 or 60 is below 50% of
the value preset in parameters 309, 312 and 315 Terminal, Minimum
Scaling.
WARNING/ALARM 4
MAINS IMBALANCE
Phase missing on the input power. Check the supply voltage to the
drive.
WARNING 5
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.
Alarm/Warning Limits:
Drive 208 to 230 volt 380 to 460 volt 550 to 600 volt
VDC VAC VDC VAC VDC VAC
Undervoltage alarm 211 151 402 289 557 413
Voltage warning, low 222 159 423 304 613 443

Overvoltage alarm 425 305 798 550 975 689
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
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
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 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%. Activate ASFM (Automatic Switching Frequency Modulation) in
parameter 408, Interference Reduction Method, or reduce the carrier
frequency in parameter 407, Switching Frequency.
