Processing for smooth acceleration/deceleration can be executed by using the
advanced S-curve acceleration/deceleration function. The acceleration section is set as
a sine curve as shown in the diagram below.
Each section of acceleration/deceleration is set as a ration using the advanced S-curve
acceleration/deceleration setting.
