LAUNCHXL-F280025C: Motor Control SDK Universal Project, level 4 current control mode

Hi,

Build Level #3 is for evaluating closed current loop. You are wanting to control Iq_ref and Id_ref in the diagram below? Or something else?

Best,

Kevin

I found same question.

but,  Idq_out_A.value[1] can not be directly modified.

Dear, Kevin

Is there any way to use the encoder and Hall sensor together?

Torque mode does not work well because it is difficult to find an accurate electrical angle if it is turned only with an encoder.

Is there a way to calibrate the encoder using a hall sensor?

Best,

Hwang

Hi Hwang,

This is not supported in the software by default. i.e. you cannot enable both MOTOR1_ENC and MOTOR1_HALL algorithms at the same time. You could make changes to the software yourself to support both or switch between them however.

It's likely that Idq_out_A is getting overwritten. If using Build #3 I see the code below, so you can try setting Idq_set_A variable instead.

    obj->IdqRef_A.value[0] = obj->Idq_set_A.value[0];
    obj->IdqRef_A.value[1] = obj->Idq_set_A.value[1];
