Before Auto-Tuning the Drive

Check the items below before Auto-Tuning the drive.
n 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.
