<1> Upper limit is dependent on parameter L8-38, Frequency Reduction Selection.
<2> The setting range is 0 to 2 in OLV/PM control mode.
<3> Default setting is dependent on parameter E1-01, Input voltage Setting.
<4> Values shown are specific to 200 V class drives. Double the value for 400 V class drives.
<5> Default setting is determined by parameter A1-02, Control Mode Setting.
<6> Parameter value changes automatically if E2-11 is manually changed or changed by Auto-Tuning.
<7> Default setting is dependent on parameter o2-04, Drive Model Selection.
