Hello. Which optimization run did you try to do? What was the error after aborting? |

Hello. What are the rated data of motor? The same as here or not? What are the rated data of tacho?
Do you mean P101=400V and actual voltage 80V at speed reference 25%? |

Hello. Field weakening is not speed-depended current limitation. Look at Basics of DC Drives, page 29. Armature voltage cannot be higher than rated voltage (in your case 400V). If you want to operate with field weakening you need to set min. field current in P103, then run optimization for field weakening. |

Sir P103=1 set.P109=0, Still Sound is coming from motor at speed ref 20% and same time arm voltage is 80V. |

Tacho voltage P741 changed to n80V.after that check motor run in field weakening. absolutely working ok.
Thank you all |
