It was approved in accordance with the bylaws of NEMA and supersedes the
20、indicated NEMA standards publication. This document supersedes ICS 7-2000. Parts 2 and 3 were essentially application information and have been tr ansferred to be part of the Application Guide for AC Adjustable Speed Drive Systems. In the interest of harmonization, Parts 4 and 6 of ICS 7-2000 have b
21、een replaced by NEMA ICS 61800-2-2005. Additionally for coordination, Part 5 of ICS 7-2000 has been replaced by NEMA ICS 61800-1-2002; and, Part 7 of ICS 7-2000 has been replaced by NEMA ICS 61800-4. Parts 4, 5, 6, and 7 are vacant. This standards publication provides practical information concernin
22、g ratings, construction, test, performance and manufacture of industrial control equipment. These standards are used by the electrical industry to provide guidelines for the manufacture and proper application of reliable products and equipment and to promote the benefits of repetitive manufacturing
23、and widespread product availability. NEMA standards represent the result of many years of research, investigation and experience by the members of NEMA, its predecessors, its Sections and Committees. They have been developed through continuing consultation among manufacturers, users and national eng
24、ineering societies and have resulted in improved serviceability of electrical products with economies to manufacturers and users. One of the primary purposes of this standards publication is to encourage the production of reliable control equipment which, in itself, functions in accordance with thes
25、e accepted standards. Some portions of these standards, such as electrical spacings and interruptin g ratings have a direct bearing on safety; almost all of the items in this publication, when applied properly, contribute to safety in one way or another. Properly constructed industrial control equip
26、ment is, however, only one factor in minimizing the hazards which may be associated with the use of electricity. The reduction of hazard involves the joint efforts of the various equipment manufacturers, the system designer, the installer and the user. Information is provided herein to assist users
27、and others in the proper selection of control equipment. The industrial control manufacturer has limited or no control over the following factors which are vital to a safe installation: a. Environmental conditions b. System design c. Equipment selection and application d. Installation e. Operating p
28、ractices f. Maintenance This publication is not intended to instruct the user of control equipment with regard to these factors except insofar as suitable equipment to meet needs can be recognized in this publication and some application guidance is given. This standards publication is necessarily c
29、onfined to defining the construction requirements for industrial control equipment and to providing recommendations for proper selection for use under normal or certain specific conditions. Since any piece of industrial control equipment can be installed, operated, and maintained in such a manner th
30、at hazardous conditions may result, conformance with this publication does not by itself assure a safe installation. When, however, equipment conforming ICS 7-2014 Page viii 2014 National Electrical Manufacturers Association with these standards is properly selected and is installed in accordance wi
31、th the National Electrical Code and properly maintained, the hazards to persons and property will be reduced. To continue to serve the best interests of users of Industrial Control and Systems equipment, the Industrial Automation Control Products and Systems Section is actively cooperating with othe
32、r standardization organizations in the development of simple and more universal metrology practices. In this publication, the U.S. customary units are gradually being supplemented by those of the modernized metric system known as the International Systems of Units (SI). This transition involves no c
33、hanges in standard dimensions, tolerances, or performance specifications. NEMA standards publications are subject to periodic review. They are revised frequently to reflect user input and to meet changing conditions and technical progress. Proposed revisions to this Standards Publication should be s

41、 SYSTEMS 1 GENERAL 1.1 Scope The standards in this part apply to drive converters, drives, and drive systems. The standards in this part apply to all other parts of ICS 7 unless otherwise specified. 1.2 Normative References The definitions and standards of NEMA Standards Publication 250, ICS 1, ICS
42、7.1, ICS 6, ICS 61800-1, ICS 61800-2, and ICS 61800-4 also apply to this part unless otherwise stated. 2 DEFINITIONS It is acknowledged that there are differences between the terminology and diagrammatic representation of an adjustable speed drive system in this document and those in NEMA ICS 61800-
43、1, -2 and -4. These are retained as they represent the historic practices used in North America. For the purposes of this standards publication, the following definitions apply: control circuit: A circuit containing those parts of a power converter which perform logic functions or which furnish cont
44、rol signals to the power circuit. Examples of functions encompassed by the control circuit are gating, sequencing, regulation, protection, control interface, and local control. (See Figure 1-2-1.) controller: See power converter. coordinated drive system: One or several drive systems operated in coo
45、rdinated fashion under the control of a system director to achieve the required control of a process. (See Figure 1 -2-1.) direct vector control: A field oriented control scheme that directly regulates the motor flux vector in order to produce controllable motor torque. Such a scheme could employ th
46、e use of Hall effect transducers or air gap flux sense windings for the measurement of the motor air gap flux with the necessary modifications to approximate the rotor flux. The rotor flux would then be used as the feedback in the direct vector control regulator. drive: A combination of the power co
47、nverter, motor, and motor mounted auxiliary devices. Examples of motor mounted auxiliary devices are encoders, tachometers, thermal switches and detectors, air blowers, heaters, and vibration sensors. (See Figure 1-2-1.) drive system: An interconnected combination of equipment which provides a means
48、 of adjusting the speed of a mechanical load coupled to a motor. A drive system typically consists of a drive and auxiliary electrical apparatus. (See Figure 1-2-1.) indirect vector control: A field oriented control scheme that indirectly regulates the motor flux vector without torque or flux feedba
49、ck. Such a scheme popularly employs the use of a shaft mounted pulse tachometer or encoder to determine rotor angular position, and torque angle for ICS 7-2014 Page 1-2 2014 National Electrical Manufacturers Association synchronous motors or rotor slip frequency for induction motors. The torque angle or slip frequency then controls the motor torque by the necessary inverse motor transformation equation. position control system: A control system which attempts to establish or maintain an exact correspondence betw
