MFET 474, Lab #3 page 1 of 13 MFET 474 Laboratory Assignment #3 Fall ‘09 Introduction to the PowerFlex 70 Objectives: In this assignment you will learn how to: •Wire PowerFlex 70 discrete I/O •Configure a 20-COMM-E module •Configure a PowerFlex 70 drive using DriveExplorer Preparation: Your Instructor will discuss the basic lab setup. Refer to the following manuals as necessary: •PowerFlex 70 Quick Start Manual •PowerFlex 70 User Manual •20-COMM-E User Manual These manuals have been posted on the MFET 474 web site. Background: It is assumed you have worked with the ControlLogix analog input module. The PowerFlex 70 AC variable speed drives are powered using 208 VAC. In this lab assignment it is very important that you follow the directions carefully and do not expose yourself to electrical shock. Whenever you are working with the PowerFlex 70 the following rule must be observed: When the PowerFlex 70’s cover is removed, the disconnect must be switched OFF AND locked in the OFF position.
