                                                                                  figure2

The second:

There is a doubt that we identify the rotor postion using the method that mentioned in the file named AN1942 is or not.

The method in AN1942:

1、Trigonometric

2、 Angle Tracking Observer

Hi edenli‌,

Q1: first, i wanna know that the POS_SIN and POS_COS in fig1,response to Usin and Ucos in fig2.

A1: Yes, they are. Please keep in mind that there are 2 revolvers interfaces on the board - so you need to pay attention which one you choose.

Q2: the second, there is a doubt that we identify the rotor position using the method that mentioned in the file named AN1942 is or not.

A2: The method used in the souce files if based on Angle Tracking Observer. You can check POSPE_GetPositionElRes()

Hope this helps!
