ALARM 79, Illegal power section configuration
The scaling card is the incorrect part number or not
installed. Also MK102 connector on the power card could
not be installed.
ALARM 80, Drive Restored to Factory Settings
Parameter settings are restored to factory settings after a
manual reset.
ALARM 91, Analog input 54 wrong settings
Switch S202 has to be set in position OFF (voltage input)
when a KTY sensor is connected to analog input terminal
54.
ALARM 92, No flow
A no-load situation has been detected in the system. See
parameter group 22-2.
ALARM 93, Dry pump
A No-Flow situation and high speed indicates that the
pump has run dry. See parameter group 22-2.
ALARM 94, End of curve
Feedback stays lower than the setpoint which may indicate
leakage in the pipe system. See parameter group 22-5.
ALARM 95, Broken belt
Torque is below the torque level set for no load, indicating
a broken belt. See parameter group 22-6.
ALARM 96, Start delayed
Motor start has been delayed due to short-cycle protection
active. See parameter group 22-7.
WARNING 97, Stop delayed
Stopping the motor has been delayed due to short cycle
protection is active. See parameter group 22-7.
WARNING 98, Clock fault
Clock Fault. Time is not set or RTC clock (if mounted) has
failed. See parameter group 0-7.
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 adjustable frequency drive type code must
be restored in the EEPROM. Remember to select ‘Save to
EEPROM’ to complete.
