Many Traditional Motion-Laws have Segment-Range parameters.

The Segment-Range parameters control the phases at which the mathematical-function of the motion-law starts and ends.

Default Segment Ranges
Start-Range ≥ 0	End-Range ≤ 1
0 ≤ Start Range < End Range ≤ 1

Segment-Range parameters do NOT change the Segment-Width.

One application of Segment-Range is to design Asymmetrical Motions - see below.

The images below show the acceleration graph of a Modified Sinusoid motion-law with different Segment-Range parameter values.

Note: the Segment-Width does not change.

STANDARD Modified Sinusoid

Modified-Sinusoid - 20% clipped from its Start.

Modified-Sinusoid - 20% clipped from its End.

Use an Asymmetric Modified-Sinusoid to accelerate rapidly and decelerate more gradually, or vice versa.

You split one Symmetric Modified-Sinusoid segment into two segments, and then use the Segment-Range parameters to change the phase of the crossover to design the Asymmetric Modified-Sinusoid.

In the image below, we compare an Asymmetric Modified Sinusoid (0 - 180º) with a Symmetric Modified Sinusoid (180 - 360º) motion-law.

The crossover of the Asymmetric Modified-Sinusoid is at 60º, and the crossover of the Symmetric Modified-Sinusoid is at 270º.

Asymmetrical Mod-Sine Segments :

Segment 1

Machine angle : ( of total Asymmetric motion-law )

Displacement : ( of total Asymmetric Displacement )

Start-Range = 0 ; End Range = 0.5

Segment 2

Machine angle : ( of total Asymmetric motion-law )

Displacement : ( of total Asymmetric Displacement )

Start-Range = 0.5 ; End Range = 1.0

Characteristics Values: Asymmetric and Symmetric Compared.
