• The drive is used in V/f Control and other Auto-Tuning selections are not
possible.
• Drive and motor capacities differ.
• Tunes the drive after the cable between the drive and motor has been replaced
with a cable over 50 m long. Assumes Auto-Tuning has already been
performed.
• Should not be used for any vector control modes unless the motor cable has
changed.

Rotational Auto-Tuning for V/f
Control
T1-01 = 3
• Recommended for applications using Speed Estimation Speed Search or using
the Energy Saving function in V/f Control.
• Assumes motor can rotate while Auto-Tuning is executed. Increases accuracy
for certain functions like torque compensation, slip compensation, Energy
Saving, and Speed Search.

The necessary information is usually listed on the motor nameplate or in the motor test report provided by the motor
manufacturer. Also refer to page
for details on Auto-Tuning processes and selections.
