Danfoss VLT Brook Crompton Motor FCM 300, Design Manual

Page: 90 / 102

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.
NOTICE
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 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 the
motor itself.
Contact your Danfoss supplier.
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):
ALARM: 37
Internal error (INTERNAL ERROR):
An error has occurred in the SYSTEM. Contact your Danfoss
supplier.
