TMS320F280040C: InstaSPIN with two or one shunt

Part Number: TMS320F280040C
Other Parts Discussed in Thread: BOOSTXL-DRV8305EVM, LAUNCHXL-F280049C, MOTORWARE

Hi Champs,

I believe that three shunt resisters utilized for the InstaSPIN FOC.
Do we have any plan to take care of two or one shunt?

The reference is LAUNCHXL-F280049C and BOOSTXL-DRV8305EVM.

Thank you for your kind check.
Best regards,

Two shunts can be supported by InstaSPIN-FOC, but it doesn't support one shunt, and no plan to support one shunt also till now.

Hi Yanming,

Do you share the document which describes what has to be changed for two shunts?
Thank you for teaching me.

Best regards,

The setting for F28009C in motor control SDK is the same as F2806x in motorWare. You may refer to the InstaSPIN User's Guide (spruhj1h) as well.

Hi Yanming,

Thank you for your kind support.
I was able to find the descriptions how to configure the two shunts.
