A Traditional Motion-Law. Its name is often reduced to Parabolic Velocity, or Poly 23.

A motion with continuous Velocity, from start to end.

There are large Acceleration-Discontinuities, with infinite jerk, at its start and end.

It gives a low peak velocity, but a high peak Acceleration.

It has a low Jerk value at the crossover point (the mid-point).

Its Torque characteristic is very good.

SEGMENT-EDITOR: Flexible-Polynomial Control-Buttons for POLYNOMIAL 2-3

Use the Control-Buttons and the Flexible Polynomial motion-law:

Edit the Start Position

The Start-Position usually flows from the End-Position of the Previous-Segment.

Edit the End Position

Force the Start-Velocity and End-Velocity to Zero (units/s)

Deselect the Start-Acceleration, End-Acceleration, Start-Jerk, and End-Jerk Control-Buttons.

Dynamic Performance:

This Motion-Law is not recommended for applications where the period-ratio < 10,

There are large Acceleration-Discontinuities that produce an infinite Jerk at its start and end.

However, its peak velocity is very low, and jerk at crossover is low.

Pressure Angle Considerations

This is a Traditional Motion-Law that produces a relatively low pressure angle

Drive Torques

The torque characteristics of this motion law are good compared to other traditional motion-laws, when.
