Strategy current control on drv 8312-C2 kit

Other Parts Discussed in Thread: LMP8602

Hi there,

In order to control my motor with instaspin foc, I used the kit drv 8312-C2 kit and the piccolo F28069M.

Now I design my own card control, I modified the reading currents methods, I discarded Is-Total even IA-FB, IB-FB, IC-FB.

I used the op-amp LMP8602 of gain 50 for reading three phases current.

My questions is where : I-total , IA-FB, IB-FB and IC-FB intervene in InstaSpin FOC ? is it just in 'HAL_setupAdcs' --->hal.c and

clarke current scale factor?

Thank you in advance,

Best regards,

Hi Sanet,

Your post is being moved to the C2000 forum. The algorithm experts can better answer your question.

Hi Rick,

Any responses about my last post ?

I-total is not used

IA/B/C-FB: you need to use HAL setup to configure the correct ADC channels, and match the order we show in the examples.

you need to update the user.h settings for ADC and IQ VOLTAGE and CURRENT

you need to check the sign of the current flow

you should follow SPRUHJ1 chapter 5
