Position control allows the motor to run at a speed or a position.
ypedef enum
{
ST_POS_MOVE_VEL_TYPE=0, //!< velocity-determined position profile
ST_POS_MOVE_POS_TYPE //!< position-determined position profile
} ST_PosMoveProfileType_e;；
1， ST_POS_MOVE_VEL_TYPE=0 VS motion — velocity ， what is the difference ？
2，Position Control If a location submission is not completed, update the location. Is it OK?
