1-48 d-axis Inductance Sat. Point
Default value: Size related
Conversion index: 0
Run an AMA to set the value of this parameter. Edit the value manually only when the application requires a value other than
determined by AMA.
Select the d-axis inductance saturation point. The drive uses this value to optimize the performance of SynRM motors. Select the
value that matches the point where the inductance equals the mean value of parameter 1-37 d-axis Inductance (Ld) and parameter
1-44 d-axis Inductance Sat. (LdSat), as percentage of nominal current.
Parameter 1-49 q-axis Inductance Sat. Point

1-49 q-axis Inductance Sat. Point
Default value: Size related
Conversion index: 0
Run an AMA to set the value of this parameter. Edit the value manually only when the application requires a value other than
determined by AMA.
Enter the q-axis inductance saturation point. The drive uses this value to optimize the performance of IPM motors. Select the value
that matches the point where the inductance equals the average value of parameter 1-38 q-axis Inductance (Lq) and parameter 1-45
q-axis Inductance Sat. (LqSat), as a percentage of nominal current.
