<1> Default setting is determined by parameter A1-02, Control Mode Setting.
<2> The setting range is 1.00 to 300.00 in CLV and AOLV/PM control modes.
<3> Default setting is dependent on parameter E5-01, Motor Code Selection.
<4> Default setting is dependent on parameters C6-01, Drive Duty Selection, and o2-04, Drive Model Selection.
<5> Default setting is determined by the control mode for motor 2 (E3-01).
