Note: If p50162 = 1:
The EMF derived from the measured armature voltage (r52123) is used.
If p50162 = 2:
The EMF for armature current pre-control is calculated from the armature voltage selected with p50193 (the resistive
+ inductive armature voltage drop is subtracted internally).
If p50162 = 3:
The parameter selected with p50193 is used as the EMF for armature current pre-control. This setting also allows a
closed-loop DC link voltage control to be implemented.
If p50162 = 4:
The EMF for the armature precontrol (12-pulse in parallel) is calculated as follows:
r52290 * (r52167/p50119) * p50118
