Jerk at Cross-over :

This law has a high maximum-velocity, and high maximum-acceleration, but zero crossover jerk.

At the start and end of this Motion-Law, the Y-axis does not change very much with a significant X–axis change - 0.02% Y-axis with 5% X-axis change.

Therefore, to accurately reproduce the Motion-Law, it needs precise machining, a large cam, or an encoder with a high resolution. If possible, increase the segment-width by ~20% when possible to reduce the peak velocity, acceleration, and jerk values.

Dynamic Performance:

This Motion-Law is recommended in applications where the period ratio is between about 5 and 10.

Pressure Angle Considerations

This has a relatively large maximum-acceleration and maximum velocity, which will increase the maximum pressure-angle.

Drive Torques

It has a high peak torque.
