With S-curve acceleration/deceleration, the acceleration/deceleration rate
changes with time. If a smaller initial acceleration/deceleration rate is desired,
the amount of mechanical vibration can be reduced using the S-curve setting
and increasing the acceleration/deceleration rate. This is possible, however,
only as long as the maximum acceleration/deceleration rate is not exceeded.

The S-curve used for the PCU is the tertiary curve that joins the initial speed
and the target speed. If an S-curve is used, the maximum acceleration/decel-
eration will be 1.5 times that of the trapezoidal curve with the same accelera-
tion/deceleration time.
