Large A131 value will result in a big swelling. A132 is the same concept as above.

### (3) A150~a153 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.
