: Taper control tension command, F*: Tension command, D: winding diameter
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.
