◆ Auto-Tuning Type
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 90.
Note: The Auto-Tuning parameters valid for the control mode set for A1-02 are shown.
■ Auto-Tuning for Induction Motors
This feature 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
Set the data indicated in Table 4.7 before starting Auto-Tuning.
The information required for setting can be found on the motor nameplate or in the motor test report. For details on the
procedure for Auto-Tuning, refer to Subchart A-1: Simple Motor Setup Using V/f Control, or Serial Operation of
Multiple Motors on page 91 or Subchart A-2: High Performance Operation Using OLV or CLV on page 92.
