Linear taper profile
When the Pr.1286 setting is smaller than the minimum winding diameter and Pr.1286 = "9999", the winding
diameter at taper start is the minimum winding diameter.
When the minimum winding diameter is equal to or larger than the maximum winding diameter, the taper
function is invalid.
