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.
Pseudo Modified-Sinusoid motion-law from 3 Harmonics.
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.
