16、ER DRIVE SYSTEMS Part 7-302: Generic interface and use of profiles for power drive systems Mapping of profile type 2 to network technologies FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical commit

17、tees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical

18、Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental a

19、nd non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreem

20、ents of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use an

21、d are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote

22、international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated

23、 in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to I

24、EC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and e

IEC 61800-7 describes a generic interface between control systems and power d

36、rive systems. This interface can be embedded in the control system. The control system itself can also be located in the drive (sometimes known as “smart drive“ or “intelligent drive“). A variety of physical interfaces is available (analogue and digital inputs and outputs, serial and parallel interf

37、aces, fieldbuses and networks). Profiles based on specific physical interfaces are already defined for some application areas (e.g. motion control) and some device classes (e.g. standard drives, positioner). The implementations of the associated drivers and application programmers interfaces are pro

38、prietary and vary widely. IEC 61800-7 defines a set of common drive control functions, parameters, and state machines or description of sequences of operation to be mapped to the drive profiles. IEC 61800-7 provides a way to access functions and data of a drive that is independent of the used drive

39、profile and communication interface. The objective is a common drive model with generic functions and objects suitable to be mapped on different communication interfaces. This makes it possible to provide common implementations of motion control (or velocity control or drive control applications) in

40、 controllers without any specific knowledge of the drive implementation. There are several reasons to define a generic interface: For a drive device manufacturer Less effort to support system integrators Less effort to describe drive functions because of common terminology The selection of drives do

41、es not depend on availability of specific support For a control device manufacturer No influence of bus technology Easy device integration Independent of a drive supplier For a system integrator Less integration effort for devices Only one understandable way of modeling Independent of bus technology

42、 Much effort is needed to design a motion control application with several different drives and a specific control system. The tasks to implement the system software and to understand the functional description of the individual components may exhaust the project resources. In some cases, the drives

43、 do not share the same physical interface. Some control devices just support a single interface which will not be supported by a specific drive. On the other hand, the functions and data structures are often specified with incompatibilities. This requires the system integrator to write special inter

44、faces for the application software and this should not be his responsibility. Some applications need device exchangeability or integration of new devices in an existing configuration. They are faced with different incompatible solutions. The efforts to adopt a solution to a drive profile and to manu

45、facturer specific extensions may be unacceptable. This will reduce the degree of freedom to select a device best suited for this application to the selection of the unit which will be available for a specific physical interface and supported by the controller.

The drive profile types for CiA 402 1 , CIP Motion TM2 , PROFIdrive 3and SERCOS interface TM4are mapp

47、ed to the generic interface in the corresponding annex. The annexes have been submitted by open international network or fieldbus organizations which are responsible for the content of the related annex and use of the related trademarks. The different profiles types 1, 2, 3, 4 are specified in IEC 6

48、1800-7-201, IEC 61800-7-202, IEC 61800-7-203 and IEC 61800-7-204. This part of IEC 61800-7 specifies how the profile type 2 (CIP Motion TM ) is mapped to the network technologies DeviceNet TM5 , ControlNet TM6and EtherNet/IP TM 7 . IEC 61800-7-301, IEC 61800-7-303 and IEC 61800-7-304 specify how the

49、 profile types 1, 3 and 4 are mapped to different network technologies (such as CANopen 8 , EtherCAT TM9 , Ethernet Powerlink TM 10 , PROFIBUS 11 , PROFINET 12and SERCOS interface). 1CiA 402 is a trade name of CAN in Automation, e.V.
