% 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.

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.

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 increased by the value of the attribute. This attribute is used by the drive to compensate for changes in the optimal Commutation Offset angle that can occur as a function of motor current.
