When using s32k144 to debug a new motor, and in closed-loop, the speed runs off, and drvFOC.iDQReqInLoop.fltArg2 becomes negative. However, when drvFOC.iDQReqInLoop.fltArg2 is multiplied by 0.35, it can run normally. How should I adjust the speed loop, Current loop or observer

Hi,

Thank you so much for your interest in our products and for using our community.

You can refer to the app note Motor Control Application Tuning (MCAT) Tool for 3-Phase PMSM (AN4642), which will help you with parameter tuning when proposing a new motor.

Hope it helps you.

Have a nice day!
