TIDA-00914: Software for TIDA-00914

Geon Kim

Part Number: TIDA-00914
Other Parts Discussed in Thread: AMC1306E25, TMDSCNCD28379D, , TMS320F28377D

Hello,

We are planning to apply the AMC1306E25 Delta-Sigma Modulator device for the phase current sensing in our new PMSM motor control project.

I have found out that TIDA-00914 uses the TMDSCNCD28379D Delfino Control Card for its motor control.

In order to make reference to in our new project and evaluate the AMC1306E25, I need the software for the TMDSCNCD28379D Delfino Control Card associated with this TI design.

How can I get the software?

Thank you for your guidance.

Hello Kim, Thanks for your interest in TIDA-00914.

Ready software support is not available online for this TI design. However like mentioned in section 5.1 of the design guide we have used code from TI control suite and did modifications to it. The base code can be found using below guide.

Sensorless Field Oriented Control of 3-Phase Permanent Magnet Synchronous Motors Using TMS320F2833x

The ADC Macro in this code has been replaced with SDFM code. A good place to start for the SDFM code will be the design drive software (www.ti.com/.../DESIGNDRIVE).

Best Regards,

Pawan

Dear Pawan,

Thank you for your review.

It is stated in the design that "The center of the SINC filter window is synchronized to the center of the PWM pulse as shown in Figure 38. This ensures that no switching noise gets into the SINC filter window and the
measured current is the average current."

How can I synchronize the center of the SINC filter window to the center of the PWM pulse as shown in Figure 38?

Would you please provide some code sniffets for this synchronization with respect to the TMS320F28377D device?

I appreciate your guidance.

Hello Kim,

Details on SINC filter synchronisation can be found in section 13.1.2 of the TMS320F2837xD technical reference manual.

For more support with respect to software please re-post this query on the C2000 microcontrollers forum. (link below)
