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 Start-Up
Flowcharts on page 120.
Note: Only the Auto-Tuning parameters valid for the control mode set in A1-02 are shown.
n Auto-Tuning for Induction Motors
This feature automatically sets the following parameters for induction motors automatically:
• Motor parameters E1- and E2- (E3-, E4- for motor 2)
•F1- parameters for speed feedback detection (only when Closed Loop Vector Control is set)
Table 4.6 Types of Auto-Tuning for Induction Motors
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 or Subchart A-2: High
Performance Operation Using OLV or CLV on page 122 for details on Auto-Tuning processes and selections.
