具有控制单元的系统架构
电子协调的各个驱动装置共同协作，完成您的驱动任务。在多轴驱动中，各个驱动装置由更高一级的控制系统进行控制，以实现所需的协调运动。这需要控制器与驱动装置之间进行周期性数据交换。控制单元控制所有连接轴的驱动装置，并且还建立驱动装置和/或轴之间的技术联系。由于所有所需的数据都存储在控制单元中，因此无需进行传输。轴间连接可以在控制单元内部建立，并且可以使用鼠标在 SINAMICS Startdrive 或 STARTER 配置工具中轻松配置。
SINAMICS控制单元可以自行处理简单的技术任务
CU310‑2 DP 或 CU310‑2 PN 控制单元与电源模块和单电机驱动器一起使用。
CU320‑2 DP 或 CU320‑2 PN 控制单元与所有电机模块或线路模块一起使用，用于单电机或多电机驱动。
复杂的运动控制任务可以通过支持更*的D410‑2、D425‑2、D435‑2和D445‑2控制单元来实现SIMOTION D（按性能分级）。
您可以在SiePortal和目录PM 21中获取更多关于SIMOTION的信息。
每个控制单元都基于面向对象的 SINAMICS 标准固件，包含所有常见的控制模式，并且可以扩展以满足性能要求。
驱动器控制以可配置的驱动器对象提供：
v/f控制模式存储在“矢量控制"驱动对象中，非常适合实现即使是简单的应用，如带有同步电动机的群组驱动。
紧凑型闪存卡
驱动器的功能存储在CompactFlash卡上。该卡包含所有驱动器的固件和参数设置，以项目的形式呈现。CompactFlash卡还可以存储额外的项目，这意味着在 commissioning不同类型的系列机器时，可以立即访问正确的项目。当控制单元启动后，读取CompactFlash卡上的数据并加载到工作内存中。
固件组织成对象。驱动对象用于实现对线模块、电机模块、电源模块和其他通过DRIVE-CLiQ连接的系统组件的开环和闭环控制功能。
驱动对象
驱动对象是一个具有自身参数的自包含软件函数，并且在适当的情况下，具有自身的故障消息和报警。
开环和闭环控制功能的综合包
各种标准功能，如设定点输入、数据集切换、控制器优化、运动缓冲等，确保在应用时具有高度的功能可靠性和出色的灵活性。

Vector control | | Linear/parabolic V/f characteristic Constant-frequency V/f characteristic (textile) Independent voltage setpoint input

More information on reluctance motors can be found in catalog D 81.1. Position control can be selected as a function module from both Servo and Vector mode Synchronous motors (1FK and 1FT) and linear motors can be operated only in Servo mode. Permanent-magnet 1FW4 synchronous motors can be operated over the complete operating range in Vector control. |

Extended technology with SIMOTION
SIMOTION D Control Units support the coordinated motion control of multiple drives. Technology objects are implemented in addition to drive objects on these Control Units. These are grouped to form technology packages and make available extended Motion Control functions (e.g. synchronous operation, cam disk, path interpolation and others) or technological functions (e.g. a cam controller, a temperature or pressure control). The IEC 61131‑3-compliant PLC integrated in SIMOTION D Control Units means that they are not just capable of controlling sequences of motions, but the entire machine including HMI and I/Os.
You can obtain more information about SIMOTION in SiePortal and Catalog PM 21.
BICO technology
Every drive object contains a large number of input and output variables which can be freely and independently interconnected using Binector Connector Technology (BICO). A binector is a logic signal which can assume the value 0 or 1. A connector is a numerical value, e.g. the actual speed or current setpoint.
Basic positioner (EPOS)
The EPOS basic positioner provides powerful and precise positioning functions. Due to its flexibility and adaptability, the EPOS basic positioner can be used for a wide range of positioning tasks. The functions are easy to use during both commissioning and operation, and the comprehensive monitoring functions are very powerful. Many applications can be implemented without external position control systems.
More information about the basic positioner (EPOS) is provided in the section Technology functions.
EPOS is only available for SINAMICS S120 booksize and booksize compact.
SINAMICS Drive Control Chart (SINAMICS DCC)
SINAMICS DCC expands the scope of device functions by means of freely available closed-loop control, arithmetic and logic blocks and offers a means by which proprietary technological functions can be graphically configured in the SINAMICS drive system. In addition, local data processing in the drive supports the implementation of modular machine concepts and results in an increase in the overall machine performance.
More information about the Drive Control Chart (DCC) is provided in section Engineering tools.
SINAMICS Technology Extensions (SINAMICS TEC)
The SINAMICS TEC are configurable functions or Siemens technologies that can be added to extend firmware functions. The extensions implement high-performance and targeted application-specific tasks for different areas, e.g. storage and retrieval machines.
More information about Technology Extensions (TEC) is provided in section Technology functions.
Integral safety functions (Safety Integrated)
The Control Units support comprehensive safety functions.
The integrated safety functions are the Safety Integrated Basic Functions
and the Safety Integrated Extended Functions that require a license
STO = Safe Torque Off
SS1 with SBR/SAM = Safe Stop 1 with Safe Brake Ramp/Safe Acceleration Monitor
SS2 = Safe Stop 2
SBC = Safe Brake Control
SOS = Safe Operating Stop
SLS = Safely-Limited Speed
SSM = Safe Speed Monitor
SDI = Safe Direction
SLA = Safely-Limited Acceleration
SBT = Safe Brake Test
and Safety Integrated Advanced Functions
(Abbreviations in accordance with IEC 61800‑5‑2)
If the integrated safety functions are used, licenses, supplementary system components such as TM54F Terminal Modules, or suitable safety controls will be necessary.
More information about the integrated safety functions is provided in section Safety Integrated.
Diagnostics optimally supported by trace function
驱动对象相关的输入和输出变量的时间特性可以通过集成的跟踪功能进行测量，并使用STARTER调试工具进行显示。可以同时跟踪多个信号。记录可以根据自由选择的边界条件触发，例如输入或输出变量的值。
