Selection Guide
Introduction
Welcome to the EPC Encoder Selection Guide. The process of selecting
an encoder for your motion system is not as simple and straightforward
as it might seem at first glance since there are a large number
of variables that must be considered, most of which are dependent
upon factors outside of the encoder itself. Some examples:
- Since encoders are most often used as feedback devices, what information
does your system need?
- At what point or points in the overall process is feedback appropriate?
- What are the environmental conditions that the encoder will be
subjected to?
As a result of these types of considerations, the purpose of this
guide is not to provide the answer, but rather to provide you guidance
in choosing which one of EPC's wide range of solutions will best
meet your requirements. Let's get started!!
Selection Criteria
Your motion system will usually dictate what set of selection criteria
are most important to you. These criteria usually fall into one
of the following broad categories. Select the one that is most important
to you:
