S-curve character-
istic time at accel-
eration start
When the S-curve characteristic time is
set, the accel time will increase by only
half of the S-curve characteristic times
at start and end.
The S-Curve characteristic time at start
and end of deceleration is fixed to 0.2
sec and can not be changed.
