For the settings for the SF-V5RU refer to page 2-74.
According to the Pr. 71 setting, the range of the motor constant parameter setting values and units
can be changed. Set the Pr. 71 "Applied motor setting" according to the motor to be used and the
motor constant setting range. (For other setting values of Pr. 71, refer to page 5-434.)

and tuning data can be stored according to settings.
Set "1" or "101".
1: Performs tuning without rotating the motor.
(Excitation noise occurs at this point.)
0
101: Performs tuning without rotating the motor.
The motor can rotate up to the speed near the rated
motor frequency.
