General Features
This application uses a virtual axis as a master so the correction movements between the axes InFeed and Knife become independent from each other.
Phase Correction in Cutting for Horizontal Balers
What does this application do?
This is a simplified application for phase correction in cutting horizontal balers machines using an electronic cam. This application can be especially useful on horizontal packaging machines or some other type of cutting-on-the-fly machines.

Is this application relevant to me?
This application can be used in cutting-on-the-fly machines, horizontal packaging, or any other type of application where an electronic cam with position correction is required. The application can be used as a complement to some existing code libraries.

Implementation Guide

- Step 4
- Step 5
Step 1
Generate the appropriate cam profile for the application. The following images show an example of a cam that performs a dwell moment as well as a linear velocity step in the middle of the curve. This is done within the “Cam Profile” of the MAPC instruction.
Step 2
In the CAM profile, identify the point where the blade would be in contact with the material (see red arrow in the image). Typically the linear speed stage is where the cutting moment takes place.
Step 3
In the “MAPC” Electronic Cam instruction adjust the “Cam Position” parameter so that the cut-off point matches the appropriate cam curve response.
Step 4
Once we have made the adjustments for both Master” and Cam Lock Positions, we can now set up the Knife Phase Correction routine.
For this a “Motion Arm Registratio” instruction is used to record the knife position at the time of detection of the Registration Mark.
In this instruction the registration mark detection window can be adjusted if it is necessary to discriminate detections outside the appropriate position range.
Step 5
Continuing in the same routine “Knife_Phase_Correction”, we have the code to obtain the Correction Error through Set/Get System Value instructions; once this value is calculated, the correction is performed through an Incremental Movement.
