概述
PROFIdrive – the standardized drive interface for
PROFINET and PROFIBUS
Profidrive将设备的行为和技术定义为
访问连接到的电动驱动器的内部设备数据
Profinet和Profibus - 来自基本频率逆变器
up to high-performance servo controllers.
它详细描述了通信功能的实际使用
tions - 从奴隶到奴隶数据传输，等距和时钟周期
synchronization (isochronous mode) in drive applications.
In addition, it specifies all device characteristics which influence
interfaces connected to a controller over PROFINET or
Profibus。这还包括状态机（序列
控制），编码器接口，值的缩放，定义
标准电报，访问驱动器参数等。
The PROFIdrive profile supports both central as well as distrib-
USTED运动控制概念。
What are profiles?
For devices and systems used in automation technology, profiles
define properties and modes of behavior. This allows manufac-
Turers和用户定义通用标准。设备和系统 -
tems that comply with such a cross-manufacturer profile, are in-
teroperable on a fieldbus and, to a certain degree, can be
互换。
Are there different types of profiles?
在所谓的应用程序之间进行区分
配置文件（一般或特定）和系统配置文件：
•
Application profiles (also device profiles) predominantly refer
to devices (e.g. drives) and include and agreed selection
关于巴士通信以及特定的设备
applications.
•
System profiles describe classes of systems, including master
功能，程序接口和集成资源。
Is PROFIdrive fit for the future?
PROFIdrive has been specified by the PROFIBUS and
PROFINET International (PI) user organization, and is specified
作为适合未来通过标准的标准
IEC 61800-7。
基本理念：保持简单
The PROFIdrive profile tries to keep the drive interface as simple
尽可能且没有技术功能。后果
这种理念，引用模型以及功能
and performance of the PROFINET/PROFIBUS master have ei-
没有影响或仅对驱动界面的影响低。
一个驱动器配置文件 - 不同的应用程序类
The integration of drives into automation solutions depends very
strongly on the particular drive application. In order to be able to
address the complete, huge bandwidth of drive applications –
从基本频率逆变器到同步多轴
systems with a high dynamic performance – using just one pro-
file, PROFIdrive defines six application classes, to which most
drive applications can be assigned:
•
Class 1 – standard drives (for example pumps, fans, agitators
ETC..）
•
Class 2 – standard drives with technological functions
•
第三类 - 定位驱动器
•
Class 4 – motion control drives with central, higher-level
运动控制智能和专利位置控制
概念“动态伺服控制”
•
Class 5 – motion control drives with central, higher-level
运动控制智能和位置设定点接口
•
第6类 - 具有分布式运动控制的运动控制驱动器
intelligence integrated in the drives themselves

Design
The device model of PROFIdrive
Profidrive定义了基于功能模块的设备模型
which cooperate in the device and generate the intelligence of
the drive system. These modules have objects assigned to them
which are described in the profile and are defined with respect
to their functions. The overall functionality of a drive is therefore
described through the sum of its parameters.
In contrast to other drive profiles, PROFIdrive defines only the
access mechanisms to the parameters as well as a subset of
profile parameters (approx. 30) such as the fault buffer, drive
control and device identification.
所有其他参数都是供应商特定的，它为驱动器提供了
ufacturer在实施功能方面的灵活性很大
modules. The elements of a parameter are accessed acyclically
via data records.
作为通信协议，Profidrive使用DP-V0，DP-V1，
and the DP-V2 expansions for PROFIBUS including the functions
"Slave-to-Slave Communication" and "Isochronous Operation",
or PROFINET IO with real-time classes RT and IRT.
