is there a code example about analysising sine-cosine signal of kmz60?

xiangxu860 — Tue, 07 Feb 2017 03:08:33 GMT

recently i use KMZ60 to get the rotor position of motor. there are two signals : sin(theta) and cos(theta).

i use look-up table method to get the value of arctan().but i found the precision of rotor position i get is not sufficiently high.

so is there a code example about analysising sine-cosine signal ?

thks!

Hi, Xu,

Can you attach the user manual or data sheet of the KMZ60 here? I can not download it from public website of NXP.

After I get the doc, I will have a review.

BTW, do you know whether NXP provide library to track the rotor position?

I'm so sorry to reply you now .

the attachments below are documents about KMZ60.

i don't know if NXP provide library to track the rotor position,could you please help me contact with the global NXP engineer which can deal with this problem?

thanks very much!
