This System Technical Guide (STG) can be used for all projects that use pumps and motors. Water application
projects are one of the most important ones due to the signicant numbers of pumps, and the importance of
pump function in the process. Therefore a wastewater application is developed at the end of the document to
illustrate the recommendations given in the previous chapters.
The System Technical Guide does not intended to replace any specic product documentation. Readers are
considered to have already known how to use the products described In this STG.
Purpose
Preliminary
STG- Pumps and motors management
1-Introduction
The aim of this STG (system technical guide) is to provide recommendations, guidelines, and examples to help
you develop the best application for pump and motor control.
The guide targets especially the medium size process control application setting up a mix of cost effective and
advanced motor control systems. The three main values of these applications are:
Ease of design -
Ease of maintenance -
Ease of extension -
More complex applications using intelligent Motor Control Centers (iMCC) or MV motors are not targeted by
this technical guide. In the same way compact pumping applications using ATV61 multi-pumps cards are not
described below. Additional technical guides will be provided for these applications.
The guide is structured in terms of different phases of the application life cycle:
Selection phase b
The guide proposes criteria to select the most appropriate solution for motor control and connection type. The
aim is to build an automation architecture that integrates motor control solution and to propose guidelines that
will improve the effectiveness of the design phase.
Design phase b
A system architecture is described and used in all the following chapters. Hardware wiring diagram and software
architecture owchart are presented. At this stage, all components from SCADA system to starters are combined
together to build a motor control application. Therefore, the data to be exchanged between components has to
be clearly dened.
Conguration phase b
Recommendations are provided to facilitate the conguration of the system using dedicated software.
The data exchanged between components are congured in the same way.
Implementation phase b
Management of the various starters requires dedicated functions and objects in the PLC, SCADA and
HMI applications. Several software packages are designed for these applications. And detail information about
programming with these software is provided in this chapter..
Operation phase b
An effective motor control application has to provide relevant diagnostic and process control features to help
the operation of the plant. Motor control diagnostic and control information is listed in this chapter.
