Other Follower Parameters
The orientation (edge or center) of “Home,” changes in the “Home” position and
changes made on the fly, are determined by the following parameters:
Edge/Center Based Profile (CP-24)
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 illus-
trates 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.

“Home”
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 auto-
matically when the Follower mechanism is in the center of the web.
