Reset messages appear in the second line
of the display, and alarm messages appear
in the third line of the display, see example
below:
ALARM
TRIP
UNDERVOLTAGE
Automatic restart (AUTO START):
When "automatic reset" is selected as
reset function, the message states that the
®
VLT frequency converter is trying to
restart automatically after cutting out. The
restart time depends on parameter 312.
Undervoltage (UNDER VOLTAGE):
Fault code 3
The intermediate circuit voltage is below
the inverter's undervoltage limit, see table
p. 125.
Overvoltage (OVER VOLTAGE):
Fault code 2
The intermediate circuit voltage is above
the inverter's overvoltage limit, see table
p. 125.
Current limit (CURRENT LIMIT):
Fault code 9
The motor current has exceeded the value
in parameter 209 for longer than permitted
in parameter 310.
Overcurrent (OVER CURRENT):
Fault code 4
The inverter's peak current limit (approx.
250% of rated current) has been exceeded
for more than 7-11 sec. (trip locked).
Earth fault (GROUND FAULT): Fault
code 5
Discharge from the output phases to earth,
either in the cable between the VLT
frequency converter and motor or in the
motor (trip locked).

Trip (TRIP):
®
The VLT frequency converter has cut out,
and manual reset is required. Manual reset
can be the reset key on the keyboard, a
digital input (terminal 16, 17 or 27) or bit 07
in the control word (RS485).
Trip locked (TRIP LOCK):
®
The VLT frequency converter has cut out
and can only be reset after the mains
voltage is switched off. After the mains
voltage is cut back in, manual reset is
required.
Alarm messages
Overtemperature (OVER TEMP.):
Fault code 6
An excess temperature has been meas-
ured inside the VLT
making a cooling off period necessary
before reset is possible. (Trip locked).
Inverter overloaded (OVER LOAD):
Fault code 7
The electronic thermal inverter protection
reports that the VLT
has cut out due to overload (excessive
current for too long). The electronic thermal
inverter protection counter has reached
100%.
Motor overloaded (MOTOR TRIP):
Fault code 8 and 15
According to the electronic thermal motor
protection, the motor is too hot. The alarm
only comes if "trip" has been selected in
parameter 315. See curve p. 130.
Inverter fault (INVERTER FAULT):
Fault code 1

power section, contact Danfoss.
