<1> Default setting value is determined by parameter o2-04, Drive Model Selection.
<2> This setting value depends on rated output current in models 2
0414: 2.00 in Open Loop Vector Control.
<4> Values shown are specific to 200 V class drives. Double the values for 400 V class drives.
<5> This setting value depends on rated output current and V/f pattern selection in parameter E1-03.
