CCS/tms320f28069: software detection of BLDC wiring fault

Part Number: TMS320F28069
Other Parts Discussed in Thread: MOTORWARE

Tool/software: Code Composer Studio

Hello all,

We are working on a BLDC project using TI instaspin FOC. we have a motor controller with a TMS320F28069 Piccolo chip. 

Its interesting for us to be able to know if there is a hardware fault with the motor, prior to start up. sort of a check that occurs everytime at bootup.

What we would like to know if there is a short circuit between any 2 phases of the BLDC and how to detect that. are there any suggestions as a reliable way to implement it?

regards,
