Ramps Page Description (continued)
Puller
Four choices of ramp styles are available. S-Curves provide less wear on the
mechanics of the puller by use of smoothing at the beginning and end of the ramp.
The middle of the profile is linear but uses a steeper gradient to compensate for
the smooth ends. No matter which option is chosen the time and distance for a
speed change will be the same
• Linear - rate of change is constant throughout the speed change
• 1/4 S-Curve - linear portion is 1.143 x average acceleration
• 5/8 S-Curve - linear portion is 1.455 x average acceleration
• S-Curve - linear portion is 2 x average acceleration
