Distribution of the interpolation points
• The saturation characteristic is represented by 17 interpolation points linearly distributed on
the X axis (
• Interpolation point 17 represents 100 % of the maximum motor current in the process (
• The following diagram shows the saturation characteristic stored in the »Engineer« motor
catalogue for the Lenze motor "MCS12H15" as an example:
