A floating point value that specifies the phase-to-neutral, d-axis, inductance of an
interior permanent magnet motor.

0 100 % Nominal Inductance
An array of floating point values that specify the amount of d-axis flux saturation
in the motor at rate current. The units for d-axis flux saturation values are
percent of Nominal Inductance, such that a value of 100% means no saturation,
and 90% means the inductance is 90% of its value at zero current given by the PM
Motor Ld Inductance attribute. The PM Motor Ld Flux Saturation value specifies
the d-axis flux saturation at 100% of the Continuous Current Rating.

Commutation Offset Compensation
Usage Access Data
Type
Default Min Max Semantics of Values
Optional - CE SSV REAL 0 0 - Electrical Degrees
This value specifies the change in the Commutation Offset value in units of
electrical degrees as a linear function of current. When the Iq current is +100% of
rated continuous current, the Commutation Offset value is decreased by the value
of this attribute. When the Iq current is -100% the Commutation Offset is
