Using a Multiple Pole Resolver

We were thinking of switching to a multiple pole resolver. Our motor has 3 pole pairs, so we were thinking of switching to a 3 pole resolver. In one revolution, this would make it look like we are taking 3 revolutions in KMS code. 


I think all I would need to do, is not multiply the mechanical angle by the number of pole pairs to calculate the electrical angle. The 3 pole resolver would make my electrical angle equal to my resolver angle? Is this correct?


I have already successfully replaced the QEI block, and have been running fine with a 1 pole resolver.
