This parameter determines the S curve strength. A large S curve time will give the
smoothest transition between speed changes. Please note the S curve settings
increase the actual acceleration/deceleration times as follows:
Actual acceleration time = [½(Pr.01-24) + ½(Pr.01-25) + Pr.01-12]

The S curve is disabled when Pr. 00-13 (Auto Acceleration/Deceleration Speed
Selection) is set to Auto or Pr 01-12 to 01-19 (acceleration/deceleration times) is set to
0.
