the motor constant parameter setting values and units can be changed. (For other setting values of Pr.71, refer to

NOTE
• When the SF-V5RU (other than the 1500 r/min series) is used, be sure to perform auto tuning after setting "1, 13, or 14" in
Pr.71 and setting Pr.83 and Pr.84.
• When Pr.11 DC injection brake operation time = "0" or Pr.12 DC injection brake operation voltage = "0", offline auto
tuning is performed at the initial setting of Pr.11 or Pr.12.
• When position control is selected (Pr.800 = "3 or 5" (when the MC signal is OFF)), offline auto tuning is not performed.
• If "wye connection" or "delta connection" is incorrectly selected in Pr.71, Advanced magnetic flux vector control, Real
sensorless vector control, and Vector control are not performed properly.

Set the motor capacity (kW).
Set the number of motor poles (2 to 12).
Set this parameter under Vector control or Real sensorless vector
control.
Set the rated motor current (A).
*1
Set the rated motor voltage (V) printed on the motor's rating plate.
Set the rated motor frequency (Hz).
Pr.3 Base frequency setting is used.
Set this parameter according to the motor.
constant setting ranges, units and tuning data can be stored according
to settings.
Set "1" or "101".
1: Tuning is performed without the motor rotating. (Excitation noise
occurs at this point.)
101: Tuning is performed with the motor rotating. The motor can rotate
up to the speed near the rated motor frequency.
