Wrong sign in InstaSPIN's CLARKE_run function?

Other Parts Discussed in Thread: MOTORWARE

Hello,

I am currently working on a motor drive setup and was taking a closer look on the Clarke  transformation, which is executed in the FOC algorithm.

But there is a '+' in the implementation provided in Motorware and in MotorControl SDK which is not quite clear to me:

As far as I know the Clarke Transformation, this should be a minus... (https://de.wikipedia.org/wiki/Clarke-Transformation)

Am I missing something there or is this really a mistake?

Kind regards,
Michael
