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 the 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.
• For tuning accuracy improvement, set the following parameters when the motor constants are known in advance.

The setting is valid only when a value other than "9999" is set in both Pr.707 (Pr.744) and Pr.724 (Pr.745).
