39、s. IEC 61800-7 describes a generic interface between control systems and power drive 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 i

40、s available (analogue and digital inputs and outputs, serial and parallel interfaces, 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 implemen

41、tations of the associated drivers and application programmers interfaces are proprietary 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 wa

42、y to access functions and data of a drive that is independent of the used drive 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 implemen

43、tations of motion control (or velocity control or drive control applications) in 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 d

44、escribe drive functions because of common terminology The selection of drives does 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 f

45、or devices Only one understandable way of modeling Independent of bus technology 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 in

46、dividual components may exhaust the project resources. In some cases, the drives 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 wi

47、th incompatibilities. This requires the system integrator to write special interfaces 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 incomp

48、atible solutions. The efforts to adopt a solution to a drive profile and to manufacturer 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.
