This motion is approximately equal to the Modified-Sinusoid motion-law.

1.Select the Triple Harmonic in the Motion-Law Selector

2.Open the Segment Editor.

3.Edit the Segment Parameters:

•First Harmonic = 5.1968

•Second harmonic = 1.7690

•Third Harmonic = 0.6057

We calculate the Third harmonic for you, based on the fact that the segment always creates a Dwell-Rise-Dwell type segment.

Segment-Parameters that approximate the Modified Sinusoid motion-law.

Summary

This motion-law is continuous and symmetrical.

It is near to the traditional Modified Sinusoid Cam-Law.

However, because it has only three harmonics, it is smoother at the higher derivatives.

The maximum velocity is slightly lower and the nominal acceleration is slightly higher than the Modified-Sinusoid motion law.
