I am seeking some guidance on configuring the MCSDK to use sensor-less (Observer+PLL) as the main sensor, and hall sensors as the auxiliary sensor. Where can the FOC crossover speed be configured such that under a certain speed (eg. 200 rpm) the algorithm will switch from sensorless to sensored?
Currently, we verified that the two control methods work independently. In sensored mode, the speed feedback becomes unreliable at low speeds, as expected. However, when hall sensors are selected as the auxiliary sensor, the motor still cannot spin reliably near zero. I have looked into the following variables but did not find specific documentation on what changing them means.
Any advice would be greatly appreciated. Thank you!.

Hello @dwsytm and welcome to the ST Community.
since your question is about STM32 MCSDK, I moved your thread from the topic PMMC to "STM32 Motor Control".
