<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 OLV/PM control mode. The setting range is 0 and 1 in CLV or AOLV/PM control modes.
<3> Default setting is dependent on parameter E1-01, Input voltage Setting.
<8> Values shown are specific to 400 V class drives. Multiply the value by 1.4375 for 575 V class drives. Multiply the value by 1.725 for 690 V class
