Warnings and alarms, cont.
ALARM 11
Motor thermistor (MOTOR THERMISTOR):
If a thermistor is mounted and parameter 128 is set
to Enable [1], the FC motor will trip if the motor gets
too hot.
WARNING 12
Current limit (CURRENT LIMIT):
The current is higher than the value in parameter
221 (in motor operation).
ALARM 13
Overcurrent (OVERCURRENT):
The inverter peak current limit (approx. 230% of the
rated current) has been exceeded. The FC motor
will trip, while giving an alarm.
Turn off the FC motor and check whether the motor
shaft can be turned.
ALARM: 14
Earth fault (EARTH FAULT):
There is a discharge from the output phases to
earth, either between the inverter and the motor or
in the motor itself.
ALARM: 15
Supply fault (SWITCH MODE FAULT):
Fault in the switch mode power supply (internal
24 V supply).
Contact your Danfoss supplier.
ALARM: 16
Short-circuiting (CURR.SHORT CIRCUIT):
There is short-circuiting on the motor terminals or in
the motor itself.
Contact your Danfoss supplier.
NB! NB! NB!
NB! NB!
If shock loads occur this alarm may appear.
WARNING/ALARM 17
Standard bus timeout (STD BUSTIMEOUT)
There is no communication to the FC motor.
The warning will only be active when parameter 514
has been set to another value than OFF.
If parameter 514 has been set to stop and trip, it will
first give a warning and then ramp down until it trips,
while giving an alarm.
Parameter 513 Bus time interval could possibly be
increased.

WARNING/ALARM 18
HPFB bus timeout (HPFB BUS TIMEOUT)
There is no communication with the FC motor.
The warning will only be active when parameter
804 has been set to another value than OFF.
If parameter 804 has been set to Stop and trip, it
will first give a warning and then ramp down until
it trips, while giving an alarm.
Parameter 803 Bus time out could possibly be
increased.
WARNING 33
Out of frequency range:
This warning is active if the output frequency has
reached parameter 201 Output frequency low
limit or parameter 202 Output frequency high
limit.
WARNING/ALARM 34
HPFB error (HPFB ALARM):
The profibus communication is not working
correctly.
ALARM 35
Inrush fault (INRUSH FAULT):
This warning occurs when the unit has been
switched on too many times within 1 minute.
WARNING/ALARM 36
Overtemperature (OVERTEMPERATURE):
A warning occurs at 78°C and the FC motor
trips at 90°C. The unit can be reset when the
temperature is below 70°C.
ALARM: 37
Internal error (INTERNAL ERROR):
An error has occurred in the system. Contact your
Danfoss supplier.
