EL-S-shaped Curve's Curvature
Use of an EL-S-shaped curve allows the curvature settings [AC-08] to [AC-11] for acceleration/deceler-
ation.
Setting all the curvatures at 50 (%) makes the EL-S-shaped curve equivalent to an S-shaped curve.
When setting the pair of [AC-08] and [AC-09] or that of [AC-10] and [AC-11], divide 100(%) into 2 seg-
ments, and assign one of which to the former of the pair and the other to the latter thereof (i.e., the two
segments, if summed up, render a value up to 100%).
A setting where [AC-08] = 100 and [AC-09] = 0 makes the acceleration curve a U-shaped acceleration
curve.
