  • In case of reluctance motor, reduce [PSI Align Curr Max] MCR.

  • In case of error detected during a tune in rotation:

    • Verify the run order remain active all along the tune in rotation.

    • Increase [Acceleration] ACC and [Deceleration] DEC. They must not be set to value close to 0 s.

    • If [Nb Of Repetitions] TNBR is different from 1, decrease [2nd Id max current] IDH2.

    • If [Nb Of Repetitions] TNBR is different from 1, increase [2nd Id min current] IDL2.

    • If possible, remove the load of the motor.

    • Set back [Rotation Tune Freq] TLFR to [Nominal Motor Freq] FRS.



  • If the error continues to be triggered, decrease [Rotation Tune Freq] TLFR.

  • If possible, decrease [Nb Of Repetitions] TNBR.


Clearing: This detected error can be cleared manually with the [Fault Reset Assign] RSF.
ULF
[Process Underload]
Cause:

Process underload.

• Mechanical root cause in the application.

• Changed load cycle situation of the application.



Remedy:


  • Verify and remove the cause of the underload.

  • Verify the parameters of the [Process underload] ULD– function.


Clearing: Can be cleared with [Auto Fault Reset] ATR or manually with [Fault Reset Assign] RSF.
USF
[Supply Mains UnderV]
Cause:

Supply mains undervoltage. The measured DC bus voltage is lower than the rated voltage of the Supply Mains [Mains voltage] URES configured:

• Supply Mains power too weak.



Remedy:


  • Verify the RMS input voltage and the parameters of [Undervoltage Resp] USB.


Clearing: This detected error is cleared as soon as its cause has been removed.
