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

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

mH
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.
