Operating instructions

ALARM 243, Brake IGBT
This alarm is only for F Frame drives. It is equivalent to Alarm
27. The report value in the alarm log indicates which power
module generated the alarm:
1 = left most inverter module.
2 = middle inverter module in F2 or F4 drive.
2 = right inverter module in F1 or F3 drive.
3 = right inverter module in F2 or F4 drive.
5 = rectifier module.
ALARM 244, Heatsink temperature
This alarm is only for F Frame drives. It is equivalent to Alarm
29. The report value in the alarm log indicates which power
module generated the alarm:
1 = left most inverter module.
2 = middle inverter module in F2 or F4 drive.
2 = right inverter module in F1 or F3 drive.
3 = right inverter module in F2 or F4 drive.
5 = rectifier module.
ALARM 245, Heatsink sensor
This alarm is only for F Frame drives. It is equivalent to Alarm
39. The report value in the alarm log indicates which power
module generated the alarm:
1 = left most inverter module.
2 = middle inverter module in F2 or F4 drive.
2 = right inverter module in F1 or F3 drive.
3 = right inverter module in F2 or F4 drive.
5 = rectifier module.
ALARM 246, Power card supply
This alarm is only for F Frame drives. It is equivalent to Alarm
46. The report value in the alarm log indicates which power
module generated the alarm:
1 = left most inverter module.
2 = middle inverter module in F2 or F4 drive.
2 = right inverter module in F1 or F3 drive.
3 = right inverter module in F2 or F4 drive.
5 = rectifier module.
ALARM 247, Power card temperature
This alarm is only for F Frame drives. It is equivalent to Alarm
69. The report value in the alarm log indicates which power
module generated the alarm:
1 = left most inverter module.
2 = middle inverter module in F2 or F4 drive.
2 = right inverter module in F1 or F3 drive.
3 = right inverter module in F2 or F4 drive.
5 = rectifier module.
ALARM 248, Illegal power section configuration
This alarm is only for F Frame drives. It is equivalent to Alarm
79. The report value in the alarm log indicates which power
module generated the alarm:
1 = left most inverter module.
2 = middle inverter module in F2 or F4 drive.
2 = right inverter module in F1 or F3 drive.
3 = right inverter module in F2 or F4 drive.
5 = rectifier module.
ALARM 250, New spare part
The power or switch mode power supply has been exchanged.
The frequency converter type code must be restored in the
EEPROM. Select the correct type code in par. 14-23 Typecode
Setting according to the label on the unit. Remember to select
‘Save to EEPROM’ to complete.
ALARM 251, New type code
The frequency converter has a new type code.
