0.00 mH / real32Defines the direct axis (synchronous) inductance.
Note: This parameter is valid only for permanent magnet
motors.

0.0 deg / real32Defines an angle offset between the zero position of the
synchronous motor and the zero position of the position
sensor.
This value is initially set by the autophasing routine when
an absolute encoder or an incremental encoder with
Z-pulse is used. The value can be fine-tuned by setting
98.1 User motor model mode to Position offset or Motor
parameters & position offset.
Note: The value is in electrical degrees. The electrical
angle equals the mechanical angle multiplied by the
number of motor pole pairs.
Note: This parameter is valid only for permanent magnet
motors.
