Low Impact at Crossover is Not available in the Motion-Law Selector

Cross-Over Jerk is Zero. Thus it is good motion-law where there is backlash. It is especially useful for those high-speed mechanisms where a moderate amount of backlash cannot be avoided.

See Crossover.

The Low Impact Crossover Motion-Law is made with two Flexible-Polynomial Segments.

Start:

•Position 1 =0

•Zero Velocity

•Zero Acceleration

•Jerk = Specified

Mid-Point

•Position 0.5

•Maximum unspecified Velocity

•Zero Acceleration

•Unspecified Jerk (Becomes Zero)

End:

•Position 2 = 1

•Zero Velocity

•Zero Acceleration

•Jerk = Specified

Unspecified (default). You may choose to specify these values.

Mid-Point (default). You can make this law asymmetrical, if you move the X-axis value.
