CP-24 EDGE/CENTER BASED PROFILE
The traverse length is measured from “Home”. The Edge/Center Based Profile (CP-24)
parameter allows you to set “Home” relative to either the edge or the center of your reel or web.
The Follower mechanism moves a traverse length from that position and then returns.
To set “Home” as an edge based profile, enter “1” in CP-24. All traverse length changes occur
from the edge, in the forward direction and the “Home” position does not change. The diagram
below illustrates this profile. Traverse length changes can be made on the fly and the timing on
these changes is a crucial factor. For the timing on edge based traverse length changes, refer
to the Change Activation (CP-25) parameter.

To set “Home” as a center based profile, enter “2” in CP-24. All traverse length changes occur
from the center and the “Home” position changes to compensate for traverse length changes.
The diagram below illustrates this profile. Traverse length changes will occur automatically when
the Follower mechanism is in the center of the web.

CP-25 CHANGE ACTIVATION
The Change Activation (CP-25) parameter works in conjunction with the Edge/Center Based
Profile (CP-24) parameter. When CP-24 is set to “1” (edge based), then CP-25 determines when
changes will occur. If CP-24 is set to “2” (center based), then CP-25 has no effect.
Change Activation (CP-25) can be set to “1”, “2” or “3”. Settings “2” and “3” have a number of
variables:
