1.11 Auto-Tuning
Auto-Tuning automatically sets and tunes parameters required for optimal motor
performance.
◆ Types of Auto-Tuning
There are three types of Auto-Tuning. Select the best type of Auto-Tuning for the
application. Also refer to Auto-Tuning Procedure on page 245.
Note: Auto-Tuning cannot be performed on permanent magnet motors (IPM, SPM, etc.).
◆ Before Auto-Tuning the Drive
Check the items below before Auto-Tuning the drive.
■ Basic Auto-Tuning Preparations
• Auto-Tuning automatically determines the electrical characteristics of the motor. This is
fundamentally different from other types of Auto-Tuning features used in servo systems.
• Auto-Tuning requires the user to input data from the motor nameplate. Make sure the
information written on the nameplate is handy when Auto-Tuning the drive.
