<1> The default setting and upper limit are determined by C6-01, Drive Duty Selection, and L8-38, Frequency Reduction Selection.
<2> The setting range is 0 and 1 in OLV/PM, AOLV/PM, and CLV/PM control modes.
<3> Default setting is determined by parameter A1-02, Control Method Selection.
<4> Default setting is determined by parameter A1-02, Control Method Selection.
When A1-02 = 6 (AOLV/PM), default is 0.2
When A1-02 = 7 (CLV/PM), default is 0.02.
