Use for intended purpose

The training package for Basic Principles of Stepper Motor Drive Technology may only be used:

•For its intended purpose in teaching and training applications

•When its safety functions are in flawless condition

The components included in the training package are laid out in accordance with the latest technology as

well as recognised safety rules. However, life and limb of the user and third parties may be endangered, and

the components may be impaired, if they are used incorrectly.

The learning system from Festo Didactic has been developed and manufactured exclusively for training and

vocational education in the field of automation and technology. The respective training companies and/or

trainers must ensure that all trainees observe the safety precautions which are described in this workbook.

Festo Didactic hereby excludes any and all liability for damages suffered by trainees, the training company

and/or any third parties, which occur during use of the equipment sets in situations which serve any

purpose other than training and/or vocational education, unless such damages have been caused by Festo

Didactic due to malicious intent or gross negligence.

Preface

Festo Didactic’s learning system for automation and technology is geared towards various educational

backgrounds and vocational requirements. The learning system is therefore broken down as follows:

•Technology-oriented training packages

•Mechatronics and factory automation

•Process automation and control technology

•Robotino®– training and research with mobile robots

•Hybrid learning factories

The technology packages deal with various technologies including pneumatics, electropneumatics,

hydraulics, electrohydraulics, proportional hydraulics, programmable logic controllers, sensor technology,

electrical engineering and electric drives.

The modular design of the learning system allows for applications which go above and beyond the

limitations of the individual packages. For example, PLC actuation of pneumatic, hydraulic and electric

drives is possible.

VI © Festo Didactic GmbH & Co. KG 571861

All training packages have the same structure:

•Hardware

•Teachware

•Software

•Seminars

The hardware is comprised of industrial components and systems that are specially designed for training

purposes.

The structure of the teachware corresponds to that of the training hardware. It includes:

•Textbooks (with exercises and examples)

•Workbooks (with practical exercises, supplementary instructions and solutions)

•Exercise books (with practical exercises and supplementary explanations)

•Transparencies and videos (for dynamic instruction)

The teaching and learning media are available in several languages. They’re intended for use in classroom

instruction, but are also suitable for self-study.

Where software is concerned, computer training programs, as well as simulation, visualisation, project

engineering, design engineering and programming software, are made available.

A wide range of seminar offerings covering the contents of the training packages round off the programme

for training and vocational education.

If you have any suggestions or feedback about this manual,

please send us an e-mail at: did@de.festo.com

The authors and Festo Didactic look forward to your comments.

Introduction

This workbook is part of the learning system for automation and technology by Festo Didactic GmbH & Co.

KG. The system provides a solid basis for practice-oriented basic and further training. The training package

TP 1422 deals with the subject of Basic Principles of Stepper Motor Drive Technology.

Special emphasis is placed on the setup, function, connection, range of applications and control of a stepper

motor system on the basis of the requirements for the respective application.

A permanent workstation equipped with a Festo Didactic slotted profile plate and a short-circuit-proof power

supply unit with an output voltage of 24 V DC are prerequisites for setting up the components.

The circuits for exercises 1 to 5 are set up using the TP 1422 equipment set. For exercise 6, you also need an

I/O simulation box and an I/O SysLink cable. These two components are not included in the equipment set.

Technical data for the individual components are also available (sensors, drives, motor controllers, etc.).

Work and safety instructions

General

•Trainees should only work with the circuits under the supervision of a trainer.

•Observe the specifications included in the technical data for the individual components and in particular

all safety instructions!

•Faults which may impair safety must not be generated in the training environment and must be

eliminated immediately.

Mechanical setup

•Mount all the components securely onto the slotted profile plate.

•Observe the instructions regarding positioning of the components.

Electrical setup

•Only use extra low voltages, maximum of 24 V DC.

•Establish or interrupt electrical connections only in the absence of voltage!

•Only use connecting cables with safety plugs for electrical connections.

•Only pull the safety plugs when disconnecting connecting cables – never pull the cable.

Mounting technology

The mounting boards for the components are equipped with mounting variants A, B or C:

•Variant A, snap-in system

Lightweight components that are not subject to loads (e.g. directional control valves, sensors). Simply

clip the components into the slots on the slotted profile plate. Release the components by actuating the

blue lever.

•Variant B, bolt

Components subject to medium loads (e.g. pneumatic cylinders). These components are clamped onto

the slotted profile plate using T-head bolts. The blue, knurled nut is used for clamping and releasing.

•Variant C, screw system

For components that will be subject to heavy loads and components that are rarely removed from the

slotted profile plate (e.g. on-off valve with filter regulator). The components are fastened using socket

head screws and T-head nuts.

Training package for "Basic Principles of Stepper Motor Drive Technology"

(TP 1422)

The training package TP 1422 consists of a multitude of individual training materials. The subject of this

package is stepper motors. Individual components included in the training package TP 1422 can also be

included in other packages.

Important components of TP 1422

•Permanent workstation with Festo Didactic slotted profile plate

•Equipment sets or individual components (e.g. sensors, motors, motor controllers)

Media

The teachware for the training package TP 1422 consists of a workbook. The workbook contains the

worksheets for each of the 6 exercises, the solutions for each individual worksheet and a CD--ROM. A set of

ready-to-use exercise sheets and worksheets is included for each exercise.

Technical data for the hardware components is made available along with the training package and on the

CD-ROM.

The Festo Configuration Tool (FCT) software is also made available for the training package TP 1422. This

can be used to configure the required functions for the electric drives. The drive function is implemented

through the controller-motor-axis function chain. The software adjusts these components to each other.

You'll find further training materials in our catalogue and on the Internet. The learning system for

automation and technology is continuously updated and expanded. Transparency sets, videos, CD-ROMs,

DVDs and training programs as well as additional teachware are offered in several languages.
