●
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).

NOTES
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 "star connection" or "delta connection" is incorrectly selected in Pr. 71, Advanced magnetic flux
vector control is not performed normally.
