The voltages stated are the intermediate circuit volt-
age of the frequency converter with a tolerance of ± 5
%. The corresponding mains voltage is the intermedi-
ate circuit voltage divided by 1.35
1) VLT 5122 - VLT 5552: 817/828 VDC.
WARNING/ALARM 8
Undervoltage (DC LINK UNDERVOLT):
If the intermediate circuit voltage (DC) drops below the
inverter lower voltage limit (see table on previous
page), it will be checked whether 24 V power supply is
connected.
If no 24 V power supply is connected, the frequency
converter will trip after a given time that depends on
the unit.
Furthermore, the voltage will be stated in the display.
Check whether the supply voltage matches the fre-
quency converter, see technical data.
WARNING/ALARM 9
Inverter overload (INVERTER TIME):
The electronic, thermal inverter protection reports that
the frequency converter is about to cut out because of
an overload (too high current for too long). The counter
for electronic, thermal inverter protection gives a warn-
ing at 98% and trips at 100%, while giving an alarm.
The frequency converter
cannot be reset until the
counter is below 90%.
The fault is that the frequency converter is overloaded
by more than 100% for too long.
WARNING/ALARM 10
Motor overtemperature (MOTOR TIME):
According to the electronic thermal protection (ETR),
the motor is too hot. Parameter 128 allows a choice of
whether the frequency converter is to give a warning
or an alarm when the counter reaches 100%. The fault
is that the motor is overloaded by more than 100% for
too long. Check that motor parameters 102-106 have
been set correctly.
WARNING/ALARM 11
Motor thermistor (MOTOR THERMISTOR):
The thermistor or the thermistor connection has been
disconnected. Parameter 128 allows a choice of
whether the frequency converter is to give a warning
or an alarm. Check that the thermistor has been cor-
rectly connected between terminal 53 or 54 (analogue
voltage input) and terminal 50 (+ 10 Volts supply).
WARNING/ALARM 12
Torque limit (TORQUE LIMIT):
The torque is higher than the value in parameter 221
(in motor operation) or the torque is higher than the
value in parameter 222 (in regenerative operation).
WARNING/ALARM 13
Overcurrent (OVERCURRENT):
The inverter peak current limit (approx. 200% of the
rated current) has been exceeded. The warning will
last approx. 1-2 seconds, following which the frequen-
cy converter will trip, while giving an alarm. Turn off the
frequency converter and check whether the motor
shaft can be turned and whether the motor size match-
es the frequency converter.
If extended mechanical brake control is selected, trip
can be reset externally.
ALARM: 14
Earth fault (Earth fault):
There is a discharge from the output phases to earth,
either in the cable between the frequency converter
and the motor or in the motor itself.
Turn off the frequency converter and remove the earth
fault.
ALARM: 15
Switch mode fault (SWITCH MODE FAULT):
Fault in the switch mode power supply (internal ± 15 V
supply).
