Note!

If disproportionately high S-ramp times are set for low acceleration times, this may

result in an incorrect profile generation.

Example: v = 100 mm/s, a = 1000 mm/s

 t

acc

= 0.1 s

 t

jerk_max

= 1 s

For this reason, you must only set plausible S-ramp times (this should not exceed half the

value of t

acc

).
