Other Parts Discussed in Thread: TMDSCNCD28027F, MOTORWARE

Current we are using TMS320F28069PZ for our variable frequency drive. But we required senssorless Field oriented control in our product. So we want to check performance of new your Insta-spin ROM loaded algorithm in our product.

For that algorithm required certain input like out put voltage feedback, current feedback, motor parameter etc. I go through example code but it difficult to understand from where these input are given and how to access in ROM library.

    shailesh,

    There is quite a lot of information, so I can understand being confused about www.ti.com/instaspin

    Regarding the software architectures, this link should be helpful.

    My advice is to learn InstaSPIN-FOC & InstaSPIN-MOTION in the following way:

    1. Try the on-line InstaSPIN SIMULATION if you are so inclined

    2. Read the TRM for FOC and/or MOTION to understand the features and how the software is architected and applied in ROM on each device.

    3. Make sure you have the correct silicon on your hardware (TMS320F280: 69F, 69M, 68F, 68M, 62F, 27F, 26F) or by using a controlCARD: TMDSCNCD28027F or TMDSCNCD28069MISO with your own inverter or as a kit

    4. Install MotorWare and run C:\ti\motorware\MotorWare_1_01_00_09\MotorWare.exe

    5. Work through the labs as documented in the Lab User's Guide: C:\ti\motorware\MotorWare_1_01_00_09\docs\labs\instaspin_labs.pdf

    6. While working through the labs, reference the Doxygen Documentation (modules, drivers, and project source code)  in MotorWare.exe

    and the specific chapters in the User's Guide

    7. Post here when you have questions!
