2.4. How to Use this Guide
In order to install and operate your Elmo Harmonica servo drive, you will use this manual in
conjunction with a set of Elmo documentation. Installation is your first step; after carefully
reading the safety instructions in the first chapter, the following chapters provide you with
installation instructions as follows:
• Chapter 3, Installation, provides step-by-step instructions for unpacking, mounting,
connecting and powering up the Harmonica.
• Chapter 4, Technical Specifications, lists all the drive ratings and specifications.
Upon completing the instructions in this guide, your Harmonica servo drive should be
successfully mounted and installed. From this stage, you need to consult higher-level Elmo
documentation in order to set up and fine-tune the system for optimal operation. The
following figure describes the accompanying documentation that you will require.
