The user asked if the TMC4671 can implement position control with only hall sensor inputs. The final answer confirmed that it is possible and provided settings for the TMCL-IDE, including registers 0x52=5, 0x50=12, 0x51=12, 0x63=3, and 0x0A=150995200 (0x09000100 for U=I1, V=I2, W=I0).

Hello -
We are considering using the TMC4671 for a new BLDC motor control design. My question is whether the TMC4671 can implement position control with only hall sensor inputs, or MUST it have encoder inputs to do position control?
I have used the USB-2-RTMI module and the TMCL-IDE to configure position control with the TMC4671 using only the hall sensors. It appears to operate smoothly, although that may differ for your application.
My application is using a BLDC motor, but the following registers would apply to any motor, I believe: [Selectors] Register=Value 0x52=5 0x50=12 0x51=12 0x63=3 0x0A=150995200 ---> 0x09000100 U=I1, V=I2, W=I0
