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
5 5
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 unit.
Remember to select 'Save to EEPROM' to complete.
ALARM 251, New Type Code:
The Frequency Converter has got a new type code.
