S-curve charac-
teristic time at
acceleration 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 times at
start and end of deceleration are fixed
to 0.2 sec. and can not be changed.
