Further Description of Current Limit Profile Function
The speed/current limit profile function can be added by modifying the SOP, This feature consists
of nine set points composed of a speed and current limit value per each point that make up the
total curve. The drive follows the curve made up of the nine set points, as shown in the figure
below. The purpose of this function is to allow the user to set a maximum current limit point
associated with a specified maximum speed point. This limit is not absolute, other factors may
occur causing the control to reduce the limit, as described below.
