Turn off the FC motor and check whether the
motor shaft can be turned.
NB!:
If shock loads occur this alarm may appear.
ALARM: 14
Earth fault (EARTH FAULT):
There is a discharge from the output phases
to earth, either between the inverter and the
motororinthemotoritself.
ALARM: 15
Supply fault (SWITCH MODE FAULT):
Fault in the switch mode power supply (internal
24 V supply).
Contact your Danfoss supplier.

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.

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.
