S Curve 2-155
S-Curve Selection
S-curve is enabled by defining the time to extend the acceleration and
deceleration. The time is entered as a percentage of acceleration and
deceleration time. In this case acceleration time is 2.0 seconds. The line on
the left has s-curve set to 0%. The other lines show 25%, 50%, and 100%
S-curve. At 25% S-curve acceleration time is extended by 0.5 seconds (2.0
* 25%). Note that the linear portion of this line has the same slope as when
s-curve is set to zero.
The acceleration and deceleration times are independent but the same
S-curve percentage is applied to both of them. With S-curve set to 50%,
acceleration time is extended by 0.5 seconds (1.0 * 50%), and deceleration
time is extended by 1.0 seconds (2.0 * 50%).
