Internal Fan Fault

The circulation fan stopped operating correctly.

  • Examine circulation fan operation.

  • Re-energize the drive.

  • Examine U4-03 [Cooling Fan Ope Time] and U4-04 [Cool Fan Maintenance]. If there is damage to the circulation fan or if the performance life of the fan is expired, replace the fan.
Note:

If the drive detects this error, the terminal set to H2-01 to H2-04 = 10 [MFDO Function Selection = Alarm] will activate.
