Cycloidal is a Traditional Motion-Law.
Segment-Editor AND Blend-Point Editor
CAN specify the:
•Position at the START of the segment.
The Position motion-value usually flows from the Previous-Segment to the START of the segment.
CAN specify the:
•Position at the END of the segment.
CANNOT specify the:
The Velocity values at the Start and End [they are 0 units/s ]
The Acceleration values at the Start and End [ they are 0 units/s2 ]
The Jerk values are a function of the Positions at the Start and End of the segment, and its duration.

•Position, Velocity and Acceleration Continuity
•Velocity Coefficient: Cv = 2
•Acceleration Coefficient: Ca= ± 6.28
•Jerk Coefficient: Cj= ± 39.48
•Jerk at Cross-over: Cj(co)= ± 39.48
•Max Jerk: Displacement × Cj ÷ T3
This Motion-Law is recommended in applications where the period ratio is near to 5 when the input drive is stiff and the shaft speed does not fluctuate significantly under load. It has the good acceleration characteristics at the load and should be used in systems where low residual vibration (vibration after the end of the motion segment) is desired.
Pressure Angle Considerations
It gives a relatively large pressure angle - and so might need a large cam for a given lift and predetermined pressure angle limits, to reduce it.
This Motion-Law is recommended in applications where no sudden change of input torque is a requirement. Its torque characteristics are particularly good in relation to the other Traditional Motion-Laws when the period ratio is less than approximately 10.
