Warnings and Alarms
WARNING/ALARM 104, Mixing fan fault
The fan is not operating. The fan monitor checks that the
fan is spinning at power-up or whenever the mixing fan is
turned on. The mixing-fan fault can be configured as a
warning or an alarm trip in parameter SP-53 Fan Monitor.
Troubleshooting
•
Cycle power to the frequency converter to
determine if the warning/alarm returns.
WARNING/ALARM 122, Mot. rotat. unexp.
The frequency converter performs a function that requires
the motor to be at standstill, for example DC hold for PM
motors.
WARNING 123, Motor Mod. Changed
The motor selected in parameter 1-11 Motor Model is not
correct. Check the motor model.
WARNING 220, Configuration file version not supported
The frequency converter does not support the current
configuration file version. Customization is aborted.
ALARM 246, Power card supply
This alarm is only for enclosure size F 6x unit size
frequency converters. It is equivalent to alarm 46, Power
card supply.
The report value in the alarm log indicates which power
module generated the alarm:
1 = Inverter module to the far left.
2 = Middle inverter module in 62 or 64 frequency
converter.
2 = Right inverter module in 61 or 63 frequency
converter.
3 = Right inverter module in 62 or 64 frequency
converter.
5 = Rectifier module.
WARNING 249, Rect. low temperature
The temperature of the rectifier heat sink is lower than
expected.
Troubleshooting
•
Check the temperature sensor.
WARNING 250, New spare part
The power or switch mode supply has been exchanged.
Restore the frequency converter type code in the EEPROM.
Select the correct type code in parameter SP-23 Typecode
Setting according to the label on the frequency converter.
Remember to select Save to EEPROM at the end.
WARNING 251, New typecode
The power card or other components are replaced and the
type code has changed.
WARNING 253, Digital output X49/9 overload
Digital output X49/9 is overloaded.
WARNING 254, Digital output X49/11 overload
Digital output X49/11 is overloaded.
