Set S-curve time for acceleration/deceleration process when the speed command is applied.
According to Pr3.12 Acceleration time setup and Pr3.13 Deceleration time setup, set up
sigmoid time with time width centering the inflection point of acceleration/deceleration.

. And when the actual motor speed drops to Pr3.16 Speed zero clamp
level or below, the position control is selected and servo lock is activated at this point.
The fundamental operations except for this function (switching to the position control)
are identical to those when setup value is 1.
