DRV8312-C2-KIT: DRV8312-C2-KIT

Part Number: DRV8312-C2-KIT

Hello,

I'm trying to apply FOC to DRV8312 by means of Simulink blok diagram using TI libraries.

Here is block diagram:

Already I've got all settings done, and it works.

But I'd like to have a control of speed, and when I go into block Desired Speed:

I see the formula for RPM.

And my questions are:

- where I can define value for Speed_per_unit_scaler?

- which block/variable defines the rotation direction?

- what is maximum RPM speed I can set (is it limited somewhere?)?

- is the Desired Speed output an RPM value?

- when using R66 potentiometer how can I adjust it's gain to obtain higher speed?

- how can I adjust the start-up ramp?

- is there a possibility to use Start and Stop buttons (near R66) to on/off the motor rotation (or stop the PWMing)?

I'll appreciate any help.
