Appendix B
Out of Box Configuration for PowerFlex Drives
This appendix describes how to program a velocity profile and jerk rate.
Program a Velocity Profile
and Jerk Rate
You can use either of these motion profiles for various instructions:
• Trapezoidal profile for linear acceleration and deceleration
• S-curve profiles for controlled jerk
Definition of Jerk
The Jerk is the rate of change of acceleration or deceleration.
The jerk parameters apply only to S-curve profile moves that use these
instructions:
For example, if acceleration changes from 0 to 40 mm/s
2
in 0.2 seconds, the
jerk is:
(40 mm/s
2
- 0 mm/s
2
) / 0.2 s = 200 mm/s
