Danfoss VLT AQUA Drive FC 202 Operating Manual

The report value in the alarm log indicates which drive
module generated the alarm:
1 = Left drive module.
2 = Second drive module from left.
3 = Third drive module from left (in 4-module
module systems).
4 = Fourth drive module from left (in 4-module
module systems).
ALARM 245, Heat sink sensor
No feedback from the heat sink temperature sensor. The
signal from the IGBT thermal sensor is not available on the
power card. This alarm is equivalent to alarm 39, Heat sink
sensor. The report value in the alarm log indicates which
drive module generated the alarm:
1 = Left drive module.
2 = Second drive module from left.
3 = Third drive module from left (in 4-module
module systems).
4 = Fourth drive module from left (in 4-module
module systems).
Troubleshooting
Check the following:
•
Power card.
•
Gatedrive card.
•
Ribbon cable between the power card and the
gatedrive card.
ALARM 246, Power card supply
This alarm is only for multi-drive systems. It is equivalent to
alarm 46, Power card supply. The report value in the alarm
log indicates which drive module generated the alarm:
1 = Left drive module.
2 = Second drive module from left.
3 = Third drive module from left (in 4-module
module systems).
4 = Fourth drive module from left (in 4-module
module systems).
ALARM 247, Power card temperature
This alarm is only for multi-drive systems. It is equivalent to
alarm 69, Power card temperature. The report value in the
alarm log indicates which drive module generated the
alarm:
1 = Left drive module.
2 = Second drive module from left.
3 = Third drive module from left (in 4-module
module systems).
4 = Fourth drive module from left (in 4-module
module systems).
ALARM 248, Illegal power section conguration
This alarm is only for multi-drive systems. It is equivalent to
alarm 79, Illegal power section conguration. The report
value in the alarm log indicates which drive module
generated the alarm:
1 = Left drive module.
2 = Second drive module from left.
3 = Third drive module from left (in 4-module
module systems).
4 = Fourth drive module from left (in 4-module
module systems).
Troubleshooting
Check the following:
•
The current scaling cards on the MDCIC.
WARNING 250, New spare part
The power or switch mode supply has been exchanged.
Restore the drive type code in the EEPROM. Select the
correct type code in parameter 14-23 Typecode Setting
according to the label on the drive. Remember to select
Save to EEPROM at the end.
WARNING 251, New type code
The power card or other components have been replaced
and the type code has been changed.
Troubleshooting
•
Reset to remove the warning and to resume
