<1> Default setting is dependent on parameters C6-01, Drive Duty Selection, and o2-04, Drive Model Selection.
<2> The number of decimal places in the parameter value depends on the drive model and the ND/HD selection in parameter C6-01. This value has two
decimal places (0.01 A) if the drive is set for a maximum applicable motor capacity up to and including 11 kW, and one decimal place (0.1 A) if
the maximum applicable motor capacity is higher than 11 kW.
