Auto-Tuning

◆ 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
Flowcharts on page 90.
Note: The Auto-Tuning parameters valid for the control mode set for A1-02 are shown.

Application Condition and Benefit
Setting
• The motor can turn around during the Auto-Tuning:
T1-01 = 0 This allows the most precise control of the motor.
• Running with constant output
• Tunes the drive after the cable between the drive and
motor has been replaced with a cable over 50 m long.
T1-01 = 2
Assumes Auto-Tuning has already been performed.
• Drive and motor capacities differ.
