Default Usage
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.
100% Adjusts the height of the test pulse during position detection
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), pa-
rameter 1-44 d-axis Inductance Sat. (LdSat), and parameter 1-45
q-axis Inductance Sat. (LqSat).

Size related Ramp-up time from 0 to rated parameter 1-23 Motor Frequen-
cy.
Size related Ramp-down time from rated parameter 1-23 Motor Frequency
to 0.
0.0 Hz Enter the minimum limit for low speed.
100.0 Hz Enter the maximum limit for high speed.
100.0 Hz Enter the maximum output frequency value. If parameter 4-19
Max Output Frequency is set lower than parameter 4-14 Motor
Speed High Limit [Hz], parameter 4-14 Motor Speed High Limit
[Hz] is set equal to parameter 4-19 Max Output Frequency auto-
matically.
