CP-14 CONTROL MODE
The Control Mode (CP-14) parameter allows you to choose between either the Standard or the
Lay Adjusted options in the Follower mode of operation. You can also use Control Mode (CP-14)
to choose the Direct mode of operation. The Direct mode is used for calibration and
troubleshooting. The Follower mode of operation is used to operate your system in either the
Standard option or the Lay Adjusted option. The calculation of the Follower profile length is the
only difference between the Standard and the Lay Adjusted options. In the Level Wind
application that uses the Lay Adjusted option, one lay pitch is subtracted from the profile length
to adjust for the initial lay on the reel.
Enter “1” for the Follower Mode / Standard.
Enter “2” for the Direct Mode.
Enter “3” for the Follower Mode / Lay Adjusted.
CP-15 ENGINEERING UNITS
In a level wind application, CP-15 is your Engineering Unit (E.U.) measurement of a laypitch. In
a web scanning application, CP-15 is your E.U. measurement for a traverse length. If your
application uses the M-Traverse's setpoint flexibility to change over the operation, and you have
more than one measurement, then pick one arbitrarily. However, be sure to reference that same
measurement consistently throughout the scaling set up. In setting up the scaling, you are
simply allowing the M-Traverse to establish a conversion of encoder lines to the E.U. that you
prefer to use. Place the decimal in the location of your desired resolution (to the tens, hundreds
or thousands place). All of the other Control Parameters or Monitor Parameters that display in
E.U.s will automatically display the correct decimal position.
CP-16 LEAD PPR REEL
In a level wind application, CP-16 is the number of Lead encoder lines that the Lead Frequency
input registers as a result of one revolution of the reel. In a web scanning application, CP-16 is
the number of Lead encoder lines that the Lead Frequency input registers when the Follower
travels one traverse length. When you calculate this variable, be sure to consider all gear
reductions, belt reductions and other types of reducers.
NOTE: CP-16 can not be changed during “Run”.
Use the following procedure to check CP-16:
• Place the M-Traverse in F-Stop.
• Activate the Home Set input (clears the Lead position to zero).
• Place the M-Traverse in F-Stop.
• Display MV-43 (Lead Position).
• Move the Lead either one revolution of the reel (level wind) or one traverse length
(web scan).
• MV-43 should have the same value as CP-16.
