Auto-Tuning
◆ Types of Auto-Tuning
The drive offers different types of Auto-Tuning for induction motors and permanent magnet motors. The type of Auto-
Tuning used differs further based on the control mode and other operating conditions. Refer to the tables below to select
the type of Auto-Tuning that bests suits the application. Directions on how to execute Auto-Tuning are listed in
Flowcharts on page
107.
Note: The drive will only show Auto-Tuning parameters that are valid for the control mode that has been set to A1-02. If the control
mode is for an induction motor, the Auto-Tuning parameters for PM motors will not be available. If the control mode is for a PM
motor, the Auto-Tuning parameters for induction motors will not be available.

Setting
• The drive is used in V/f Control and other Auto-Tuning selections not possible.
• Drive and motor capacities differ.
T1-01 = 2
• 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.
• Recommended for applications using Speed Estimation Speed Search or using the Energy Saving function
in V/f Control.
T1-01 = 3
• Assumes motor can rotate while Auto-Tuning is executed. Increases accuracy for certain functions like
torque compensation, slip compensation, Energy Saving, and Speed Search.
