1-44 d-axis Inductance Sat. (LdSat)
Default value: Configuration dependent
Change during operation: False
This parameter corresponds to the inductance saturation of Ld. Ideally, this parameter has the same value as parameter 1-37 d-axis
Inductance (Ld). However, if the motor supplier provides an induction curve, enter the induction value here, which is 200% of the
nominal current.

Default value: Configuration dependent
1-45 q-axis Inductance Sat. (LqSat)
Default value: Configuration dependent
Change during operation: False
This parameter corresponds to the inductance saturation of Lq. Ideally, this parameter has the same value as parameter 1-38 q-axis
Inductance (Lq). However, if the motor supplier provides an induction curve, enter the induction value here, which is 200% of the
nominal current.
Table 65: Range:
Default value: Configuration dependent
1-46 Position Detection Gain
Change during operation: True
Adjust the amplitude of the test pulse during position detection at start. Adjust this parameter to improve the position measure-
ment.
Table 66: Range:
1-48 Current at Min Inductance for d-axis
Change during operation: False
Use this parameter to set the inductance saturation point.
Table 67: Range:
1-49 Current at Min Inductance for q-axis
Change during operation: False
Specify the saturation curve of the q-axis inductance values. The q-axis inductance value is linearly approximated to parameters
parameter 1-38 q-axis Inductance (Lq) and parameter 1-45 q-axis Inductance Sat. (LqSat).
