An error in estimating current in the BEMF observer

hi  

A strange thing happened when I was debugging the observer parameters,with the increase of rotational speed, the estimated current of axis D will be deviated from the actual current.

However, the d-axis current error (gsMC.sObserverDQ.sBemfObsrv.pParamD.f16InErrK1)is always around 0, so, it is not effective for me to adjust the D-axis parameter by debugging the observer.

So,Is the documentation wrong???

I need your help,thank you very much!!!
