Sets the current used for initial rotor position estimation as a
InitRotPosDetCur percentage of the motor rated current (E5-03). If the motor
nameplate lists an "Si" value, that value should be entered here.
Sets the current during initial polar attraction as a percentage
of the motor rated current.
