I am using ST’s Motor Control Workbench (MCW) version 6.3.2 to control a sliding door. I am using PMSM as motor and FOC as control method. PMSM has 10 pole pairs and there is a 1024 ppr incremental quadrature encoder on it (has not index pin). I am using Nucleo-G474RE, STEVAL-IHM023V3 and X-Nucleo-IHM09M2 boards.
I am having trouble with encoder alignment. if I'm not mistaken, ST MCW uses “move till aligned with phase A” method (see attachment) as the encoder alignment. But i have a mechanical limit and this will not allow the motor to perform the needed alignment movements. I have posted this in the motor control forum. Not answered yet (https://community.st.com/t5/stm32-mcus-motor-control/incremental-encoder-alignment-problem/td-p/775343)
Does ST have any plans to update MCW software to include the motionless start method into speed sensing configuration in the near future?
Can anyboady give/share source code/flow chart etc.?
Any information you provide will be gladly appreciated.
