S-curve
An S-curve is a curve where the speed profile in the jerk area can
be represented by second-order profile. This helps to reduce
motor vibration at start up and stop time as indicated by points (t1,
t3, t5, t7) in figure below.
To shorten acceleration and deceleration time the linear section
(t2, t6) is inserted in these area to maintain the maximum
accleration and so get an accleration-time (A-T) chart in
trapezoidal.
