Default Usage
100% Adjusts the height of the test pulse during position detec-
tion at start.
Enter the inductance saturation point.
100%
This parameter specifies the saturation curve of the d- and q-
100%
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).
Select the PM motor start mode.
[1] Parking
[0] Disabled Select [1] Enabled to enable the drive to catch a spinning mo-
tor.
Size related Ramp-up time from 0 to rated parameter 1-23 Motor Frequen-

0.0 Hz Enter the minimum limit for low speed.
Enter the maximum limit for high speed.
100.0 Hz
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 Frequen-
