u Types of Auto-Tuning
Select the optimal Auto-Tuning based on the conditions such as your application, control mode of the drive, and
installation environment of the motor. When selecting the Auto-Tuning to run, refer to the flowcharts shown in
Flowcharts on page 120.
Note: Only the Auto-Tuning parameters valid for the control mode set in A1-02 are shown.

Table 4.7 lists the data that must be entered for Auto-Tuning. The necessary information is usually listed on the motor
nameplate or in the motor test report provided by the motor manufacturer. For details on the procedure for Auto-Tuning,
refer to Subchart A-1: Parallel Operation of Multiple Motors by V/f Control on page 121
