Dear @KE.1​ 

I forward your question to our expert.

Just in case, it is better to have the last SDK version (which is SDK5.4.5, and very soon SDK 5.4.6)

Best regards

@Laurent Ca...​ 

May i know in your SDK 5.4.6 which support "open Loop FOC and Transition to closed LOOP FOC using HALL Sensor" method ?

thanks

The SDK itself doesn't support switching speed sensor online, but you can enable both the main feedback (sensorless) and the aux feedback (hall), and add a piece of code to switch the sensor properly.

I'm interested in that topic as well.

@Laurent Ca...​  Could you specify a little bit deeper how to switch between the both speed feedback modes? I couldn't find the right "spot" where this could be done.

Thank you very mutch!
