Setting
●
To perform tuning, set the following parameters about the motor.
Set Pr. 71 "Applied motor" according to the motor to be used. According to the Pr. 71 setting, the
range of the motor constant parameter setting values and units can be changed. (For other setting
values of Pr. 71, refer to page 5-451.)
●
For the tuning accuracy improvement, set the following parameter when the motor constant is
known in advance.
The setting is valid only when both of the Pr. 707 (Pr. 744) and Pr. 724 (Pr. 745) settings are other
than "9999".

NOTES
If PM sensorless vector control is performed, tuning cannot be performed even when Pr. 96 =
"101" is set. If MM-CF is set to the applied motor, tuning cannot be performed even when Pr. 96 =
"1, 101" is set.
