Part Number: TMS320F28P550SJ

Tool/software:

Hey,

In the description of TMS320F28P550SJ it isn't written that it's supporting instaSPIN:

But the feature list says it supports:

And in the datasheet, it depends:

I want to know what's right, what's wrong, and what the PN should be in such a case, please.

I really appreciate any help you can provide.

INSTASPIN is available on all devices in the F28P550/559 families. I think the Device Identification registers are incorrect, these devices will have a value of "2" in this field, vs "1" that is indicated in the above table. I will file a bug to get the documentation fixed, but all devices will support INSTASPIN.

Best,
Matthew

OK, thanks!

From MotorControl SDK 5.03 I saw a lot of FAST lib (if I understand correctly - InstaSPIN).

What is the difference, and when should I use each?

Correct, all of these are INSTASPIN. I think these are just starting examples, I'll need to loop in someone from the SW side to comment on intended applications for each.

Best,
Matthew

Hi,

These are pre-built libraries for the FAST sensorless algorithm. Previous C2000 devices had a library version in ROM, but F28P55x does not. You have to store and use SW version of FAST lib.

Best,

Kevin

OK, so which file should I use? Those files are from MotorControl SDK 5.03
