Operation
Note Advanced auto-tuning cannot be used in the following cases.
Use the following method to make adjustments if any of the above conditions apply, or if operation is
not satisfactory when normal auto-tuning is executed.
• Set Pn103 (Inertia ratio), and then execute one-parameter tuning or manual adjustment.
■
• The following user parameters are set automatically by advanced auto-tuning.
• The following parameters are also set automatically as required.
• If the electronic gear ratio is not set within the following range, an A042 error (parameter combina-

• When the load inertia fluctuates at 200 ms or less.
• When the load rigidity is low and mechanisms (such as belt drive inputs) tends to vibrate, or
• When the range of movement is narrow, e.g., only several rotations.
• When movement is possible only in a fixed direction.
• When P (proportional) control is used.
