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:

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 fre-
quency converter type code must be restored in the EEPROM. Select the
correct type code in par. 14-23
on the unit. Remember to select 'Save to EEPROM' to complete.
ALARM 251, New type code
The frequency converter has a new type code.
