Size related 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,
which is 200% of the nominal current.
Size related 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,
which is 200% of the nominal current.

tion at start.
100% Enter the inductance saturation point.
100% This parameter specifies the saturation curve of the d- and q-
inductance values. From 20–100% of this parameter, the in-
ductances are linearly approximated due to parameter 1-37
d-axis Inductance (Ld), parameter 1-38 q-axis Inductance (Lq),
parameter 1-44 d-axis Inductance Sat. (LdSat), and parameter
1-45 q-axis Inductance Sat. (LqSat).
[1] Parking Select the PM motor start mode.
[0] Disabled Select [1] Enabled to enable the drive to catch a motor spin-
