Program a velocity profile and jerk rate and tune
an S-Curve Profile
Use this chapter to program a velocity profile and jerk rate, and tune an S-Curve
Profile.
Jerk is the rate of change of acceleration or deceleration.
Example:
If acceleration changes from 0 to 40 mm/s
2
in 0.2 seconds, the jerk is as follows.
(40 mm/s
2
- 0 mm/s
2
) / 0.2 s = 200 mm/s
3.
Consider cycle time and smoothness when you choose a profile.
