This law has a high maximum-velocity, high maximum-acceleration, high . Only the Modified-Trapezoidal (finite jerk motions) has a greater 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 to reduce the maximum-velocity 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.
