I am working on a project to drive a door using a PMSM motor in position control mode. I am trying to add an emergency brake function. In an emergency, when the operator pushes a button, motor should brake and then return to its starting position without harming anyone.
I know there is PWMC_TurnOnLowSides() function (https://community.st.com/t5/stm32-mcus-motor-control/how-can-i-stop-the-motor-urgently/m-p/597309#M8287 ). But it is just stopping the motor, not braking. I have tried this function.
As far as I know, there is no such API in position control mode.
If I am wrong, is there an API to brake the motor in an emergency? Can anyone help me? Do you have any advice for me?
Any information you provide will be welcomed.
