(C) Motor constant parameters
PARAMETERS

GROUP
C
Setting
• To perform tuning, set the following parameters about the motor.
Differs according to the voltage class. (200 V/400 V)
For the settings for the SF-V5RU refer to page 68.
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 438.)
NOTE
• If 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.
• If Pr.11 DC injection brake operation time = "0" or Pr.12 DC injection brake operation voltage = "0", offline auto tuning is
performed considering Pr.11 or Pr.12 is set to the initial value.
• If position control is selected (Pr.800 = "3 or 5" (when the MC signal is OFF)), offline auto tuning is not performed.
• If "star 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 normally.

Name Initial value Description
80 453 Motor capacity 9999 (V/F control) Set the motor capacity (kW).
81 454 Number of motor poles 9999 (V/F control) Set the number of motor poles (2 to 12).
800 451 Control method selection 20
Set this parameter when using vector control or Real
sensorless vector control.

current
Set the rated motor current (A).
83 456 Rated motor voltage 200 V/400 V
Set the rated motor voltage (V) printed on the motor's
rating plate.
84 457 Rated motor frequency 9999
Set the rated motor frequency (Hz).
When the setting is "9999", the Pr.3 Base frequency
setting is used.
71 450 Applied motor 0 (standard motor)
Set this parameter according to the motor.
Three types of motor constant setting ranges, units and
tuning data can be stored according to settings.
96 463
Auto tuning setting/
status
0
Set "1" or "101".
1: Performs tuning without rotating the motor. (Excitation
noise occurs at this point.)
101: Performs tuning by rotating the motor. The motor can
rotate up to the speed near the rated motor frequency.
