Troubleshooting
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 indi-
cates 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 indi-
cates 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 indi-
cates 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 configura-
tion
This alarm is only for F Frame drives. It is equivalent
to Alarm 79. The report value in the alarm log indi-
cates 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 adjustable frequency drive type code
must be restored in the EEPROM. Select the correct
type code in par.14-23 Typecode Setting
5-14
the label on the unit. Remember to select 'Save to
EEPROM' to complete.
ALARM 251, New type code
The adjustable frequency drive has a new type code.
