In keeping pace with advances in PC hardware and Operating Systems, Galil has released its latest generation of software tools for OEMs looking to develop fully featured, robust solutions to the most demanding motion control applications. This paper offers a brief overview a feature that may not be immediately familiar to long time Galil users, the gcaps server.

      The goal of a mechanical system built for motion control is to accurately move or position a load.  In an ideal system, the load is rigidly coupled to, and directly driven by, a linear or rotary motor. There are many systems for which this drive method is not an option and a drivetrain is required to drive the load. Some common drivetrains include:

1. Ball or lead screws
2. Belt and pulley
3. Chain and sprocket
4. Gear trains or rack & pinion
5. Hydraulics

      Our next two-day product school is Thursday January 25, 2018 through Friday January 26, 2018 . The training will be at our headquarters in Rocklin, CA (near Sacramento).

Part 3 of 3: Superposition of Motion Profiles

Introduction

      This is the final paper of three delving into advanced electronic gearing topics in motion control.  The first two, Tension Control on Spindle Wheel and Positional Correction on Color Print Rollers in Offset Printing, dealt with both low and high bandwidth corrections by correcting for frequency and phase.

      This paper will cover how to apply electronic gearing to superimpose two motion profiles for a single axis.  Three different examples will be discussed showing the many different applications where adding two motion profiles together can simplify the system’s design.
