Motor Pilot (Observer + PLL) C1 / C2 Parameter Tuning

Hi all,

I'm currently using Motor Pilot v1.2.12 and working with Observer + PLL mode for sensorless control. I see that there are parameters C1 and C2 available for tuning, but I'm not quite sure what each of them does and how they affect the motor control.

Could someone please explain the function of C1 and C2 in this context?
Also, are there any reference documents or official resources that go into detail about these parameters?

Thanks in advance!
