MBEMF

displays the motor’s back EMF constant (Kb). This value is used for current loop controller design, BEMF compensation algorithm (see also MBEMFCOMP), and standard pole-placement velocity controller design (COMPMODE = 2 or 4). When this variable is changed, the drive will enter a no-comp state, requiring a CONFIG command (see CONFIG).

Modifying MBEMF automatically updates MKT and MKTI.
