<1> Upper limit is dependent on parameters C6-01, Drive Duty Selection, and L8-38, Frequency Reduction Selection.
<2> The setting range is 0 to 2 in CLV, OLV/PM, or AOLV/PM, control modes.
<3> Default setting is dependent on parameter E1-01, Input voltage Setting.
<4> Default setting is determined by parameter A1-02, Control Mode Setting.
<5> Parameter value changes automatically if E2-11 is manually changed or changed by Auto-Tuning.
<6> Default setting is dependent on parameters C6-01, Drive Duty Selection, and o2-04, Drive Model Selection.
<7> Default setting is dependent on parameter E5-01, Motor Code Selection.
