• Motor does not rotate during Auto-Tuning.
• Motor test report or motor data similar to Table 4.21 are available.
YES
Table 4.21 lists the data that must be entered for Auto-Tuning. Make sure the data is available before starting Auto-Tuning.
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 122 for details on the Auto-Tuning process and selection.

Basic Auto-Tuning Preparations
• Auto-Tuning requires the user to input data from the motor nameplate or motor test report. Make sure this data is available
before Auto-Tuning the drive.
• For best performance, the drive input supply voltage must be at least equal to or greater than the motor rated voltage.
Note: Better performance is possible when using a motor with a base voltage that is lower than the input supply voltage (20 V for 200 V class
models and 40 V for 400 V class models). This is particularly important when operating the motor above 90% of base speed, where high
torque precision is required.
• To cancel Auto-Tuning, press the OFF key on the HOA keypad.
• When using a motor contactor, make sure it is closed throughout the Auto-Tuning process.
