Hi Daniel,

About the model of S12ZVM_FOC_Sensorless,shown as below, i wanna make sure the IdEObsrv(Part A shown) and IqEObsrv(Part B shown) is EMF or not ?  i  thought is EMF, my reason ,EMF contains the position and speed of rotor, to get the Postion of the rotor using the arctan() Function,namely Theat=arctan(EAlpha/EBeta),

and there is another doubt that the -1*2^15 in Part C,why we multiplied the -1*2^15 with IdEObsrv?
