Danfoss VLT AutomationDrive FC 300 User Manual

9.2.1 Fault Messages - Active Filter
WARNING 1, 10 volts low
The control card voltage is below 10 V from terminal 50.
Remove some of the load from terminal 50, as the 10 V
supply is overloaded. Max. 15 mA or minimum 590 Ω.
WARNING/ALARM 2, Live zero error
The signal on terminal 53 or 54 is less than 50% of the
value set in parameters 6-10, 6-12, 6-20 or 6-22 respec-
tively.
WARNING/ALARM 4, Mains phase loss
A phase is missing on the supply side, or the mains
voltage imbalance is too high.
WARNING 5, DC link voltage high
The intermediate circuit voltage (DC) is higher than the
high voltage warning limit. The unit is still active.
WARNING 6, DC link voltage low
The intermediate circuit voltage (DC) is below the under-
voltage limit of the control system. The unit is still active.
WARNING/ALARM 7, DC overvoltage
If the intermediate circuit voltage exceeds the limit, the
unit trips.
WARNING/ALARM 8, DC under voltage
If the intermediate circuit voltage (DC) drops below the
under voltage limit, the filter checks if a 24 V backup
supply is connected. If not, the unit trips. Check that the
mains voltage matches the nameplate specification.
WARNING/ALARM 13, Over Current
the unit current limit has been exceeded.
ALARM 14, Earth (ground) fault
The sum current of the IGBT CTs does not equal zero.
Check if the resistance of any phase to ground has a low
value. Make sure to check both before and after mains
contactor. Also make sure IGBT current transducers,
connection cables, and connectors are ok.
ALARM 15, Incomp. Hardware
A mounted option is not handled by the present Control
Card SW/HW.
ALARM 16, Short circuit
There is a short-circuit in the output. Turn off the unit and
correct the error.
WARNING/ALARM 17, Control word timeout
There is no communication to the unit.
The warning will only be active when 8-04 Control Word
Timeout Function is NOT set to OFF.
Possible correction: Increase 8-03 Control Word Timeout
Time. Change 8-04 Control Word Timeout Function
WARNING 23, Internal fan fault
Internal fans have failed due to defect hardware or fans
not mounted.
WARNING 24, External fan fault
External fans have failed due to defect hardware or fans
not mounted.
ALARM 29, Heatsink temp
The maximum temperature of the heatsink has been
exceeded. The temperature fault will not be reset until the
temperature falls below a defined heatsink temperature.
ALARM 33, Inrush fault
Check whether a 24 V external DC supply has been
connected.
WARNING/ALARM 34, Fieldbus communication fault
The fieldbus on the communication option card is not
working.
WARNING/ALARM 35, Option Fault:
Contact your Danfoss supplier.
ALARM 38, Internal fault
Contact your Danfoss supplier.
ALARM 39, Heatsink sensor
No feedback from the heatsink temperature sensor.
WARNING 40, Overload of Digital Output Terminal 27
Check the load connected to terminal 27 or remove short-
circuit connection.
WARNING 41, Overload of Digital Output Terminal 29
Check the load connected to terminal 29 or remove short-
circuit connection.
WARNING 42, Overload of Digital Output on X30/6 or
Overload of Digital Output on X30/7
For X30/6, check the load connected to X30/6 or remove
short-circuit connection.
For X30/7, check the load connected to X30/7 or remove
short-circuit connection.
WARNING 43, Ext. Supply (option)
The external 24 V DC supply voltage on the option is not
valid.
ALARM 46, Power card supply
The supply on the power card is out of range.
WARNING 47, 24 V supply low
Contact your Danfoss supplier.
WARNING 48, 1.8 V supply low
Contact your Danfoss supplier.
WARNING/ALARM/TRIP 65, Control card over temperature
Control card over temperature: The cutout temperature of
the control card is 80° C.
WARNING 66, Heatsink temperature low
This warning is based on the temperature sensor in the
IGBT module.
Troubleshooting:
The heatsink temperature measured as 0° C could indicate
that the temperature sensor is defective causing the fan
speed to increase to the maximum. If the sensor wire
between the IGBT and the gate drive card is disconnected,
this warning would result. Also, check the IGBT thermal
sensor.
