Change Activation (CP-25)
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:
If CP-25 is set to “1” then all of the changes will occur when the Fol-
lower is at “Home”.
If CP-25 is set to “2” and either the Accel/Decel Length or Dwell param-
eters are changed, the changes will only occur at “Home”.
If CP-25 is set to “2” and the setpoint speed is changed (either faster or
slower), the change will occur immediately, but only if the change
occurs within the new constant pitch plateau of the profile. Otherwise
setpoint speed changes occur at “Home”.
If CP-25 is set to “2” and the traverse length is changed, the change
will occur immediately, but only if the longer change occurs within the
old constant pitch plateau and a shorter change occurs within the new
constant pitch plateau of the profile, and either change is in a forward
direction. Otherwise traverse length changes occur at “Home”.
If CP-25 is set to “2” and both the traverse length and the setpoint
speed are changed, then use the switches to make the changes and
stay within the profile parameters listed above for setpoint speed and
traverse length changes. When any of the changes are not within the
specified plateaus of the profile, then the changes will occur when the
Follower mechanism reaches “Home”. Refer to the diagrams below.
