Large  value will result in a big swelling.  is the same concept as above.
(3) ~ Curvature of EL-S-curve
When using EL-S-curve pattern, you can set the curvatures individually for acceleration
and deceleration. If all the curvatures are set to 50%, the EL-S-curve pattern will be
equivalent to the S-curve pattern.
