Warnings

124
Display massages
Warnings appear in the third line of the
display, see the example below:
Voltage low
(VOLTAGE LOW)
Voltage low (VOLTAGE LOW)
The intermediate circuit voltage (d.c.) is
below the control card's warning limit, see
table p. 125. The inverter is still active.
Voltage high (VOLTAGE HIGH):
The intermediate circuit voltage (d.c.) is
above the control card's warning limit, see
table p. 125. The inverter is still active.
Undervoltage (UNDERVOLTAGE):
The intermediate circuit voltage is below
the inverter's undervoltage limit, see table
p. 125. The inverter has stopped, and after
the time in parameter 311 there will be a
trip.
Overvoltage (OVERVOLTAGE):
The intermediate circuit voltage is above
the inverter's overvoltage limit, see table
p. 124. The inverter has stopped, and after
the time in parameter 311 there will be a
trip.
Current limit (CURRENT LIMIT):
The motor current is higher than the value
in parameter 209.
Overcurrent (OVER CURRENT):
The inverter's peak current limit (approx.
250% of rated current) has been exceed-
ed, and after 7-11 sec. there will be a trip.
Reference faults (REF. FAULT):
A fault to the analogue input signal (ter-
minal 53 or 60) when a signal type with
"live" zero" has been selected (4-20 mA,
1-5 V or 2-10 V). The warning is activated
when the signal level is below half of the
zero level (4 mA, 1 V or 2 V).
No motor (NO MOTOR):
The motor check function (para. 313)
®
MG.30.A7.02 - VLT is a registered Danfoss trademark
detects that no motor is connected to the
®
VLT frequency converter's output.
Frequency warning low
(LO FREQ WARN):
The output frequency is lower than the
value in parameter 210.
Frequency warning high
(HI FREQ WARN):
The output frequency is higher than the
value in parameter 211.
Current warning low
(LO CURR WARN):
The output current is lower than the value
in parameter 212.
Current warning high
(HI CURR WARN):
The output current is higher than the value
in parameter 213.
