Operation Theory
these areas. Once maximum velocity is met, there is a line con-
necting the acceleration s-curve and the deceleration s-cure, dem-
onstrating the maintained maximum velocity over time. This graph
is called a “Bell” curve. This speed profile improves the speed of
acceleration and also reduces the vibration of acceleration.
For a bell curve, we define its shape’s parameter as below:
Tacc: Acceleration time in second
Tdec: Deceleration time in second
StrVel: Starting velocity in PPS
MaxVel: Maximum velocity in PPS
VSacc: S-curve part of a bell curve in deceleration in PPS
VSdec: S-curve part of a bell curve in deceleration in PPS
