设计
SINAMICS G120C is a compact converter for control cabinet mounting in IP20 degree of protection where the Control Unit (CU) and Power Module (PM) function units are combined in one device.
The compact mechanical design and the high power density allow these devices to be installed in machine control enclosures and control cabinets for maximum space utilization. The SINAMICS G120C compact converter can be butt-mounted directly, without derating at temperatures up to 40 °C (104 °F).
SINAMICS G120C, frame size FSAA with BOP-2
SINAMICS G120C can be integrated into the widest range of applications, either using the integrated digital and analog inputs or via the integrated fieldbus interface (available in USS, Modbus RTU, PROFIBUS, PROFINET / EtherNet/IP versions). Especially the product versions with integrated PROFIBUS/PROFINET interface make full integration into the Siemens TIA family possible, therefore allowing the advantages of the seamless TIA product family to be fully utilized. SINAMICS G120C devices are preset in the factory so that they can be immediay connected to PROFIBUS and/or PROFINET fieldbus systems without parameterization.
SINAMICS G120C is also equipped with the safety function STO (Safe Torque Off) as standard, which is used to safely stop drives. As a consequence, machine manufacturers can simply comply with current machinery directives with minimum associated costs.
SINAMICS G120C can control asynchronous (induction) motors in the power range from 0.37 kW up to 132 kW (0.5 hp to 200 hp). Reliable and efficient motor operation is achieved by using state-of-the-art IGBT technology combined with vector control. The extensive range of functions integrated in the SINAMICS G120C also offers a high degree of protection for the converter and motor.
Line-side components
Line reactors
Line reactors smooth the current drawn by the converter and thus reduce harmonic components in the line current. Through the reduction of the current harmonics, the thermal load on the power components in the rectifier and in the DC-link capacitors is reduced as well as the harmonic effects on the supply. The use of a line reactor increases the service life of the converter.
Recommended line-side power components
Standard fuses can be used for the SINAMICS G120C. These must be dimensioned to comply with local regulations. In this chapter, you will find recommended components such as fuses and circuit breakers in compliance with IEC and UL regulations.
DC link components
Braking resistors
Excess energy in the DC link is dissipated in the braking resistor. The braking resistors are designed for use with the SINAMICS G120C. This has an integrated braking chopper (electronic switch).
Load-side power components
Output reactors
Output reactors reduce the rate of voltage rise (dv/dt) and the height of the current peaks, and enable longer motor cables to be connected.
Supplementary system components
Inligent Operator Panel IOP
Graphics-based, user-friendly and powerful operator panel for commissioning and diagnostics as well as local operator control and monitoring of SINAMICS G120C.
Basic Operator Panel BOP-2
A 2-line display to provide support when commissioning and troubleshooting the drive. The drive can be locally controlled.
Memory card
The parameter settings for an inverter can be stored on the SINAMICS SD memory card. When service is required, e.g. after the inverter has been replaced and the data have been downloaded from the memory card the drive system is immediay ready for use again. The associated memory card holder is integrated in the inverter.
PC inverter connection kit 2
For controlling and commissioning an inverter directly from a PC if the STARTER commissioning tool or SINAMICS Startdrive has been installed on the PC.
Spare parts
Shield plates
A set of shield plates is included in the scope of delivery for the motor and signal cables corresponding to the frame size of the SINAMICS G120C, and can also be ordered as spare parts.
Spare parts kit
This kit comprises four I/O terminals, one RS485 terminal, two pairs of Control Unit doors (1 × PN and 1 × other communication versions) and one blanking cover.

神经网络在PLC控制系统中的应用
关键词：PLC;PID控制器;神经网络;直流调速系统
本文是将PID控制规律融进神经网络[3]之中，实现神经网络与PID控制规律的本质结合，共同完成PID自适应调节，并用PLC实现神经网络PID自适应控制，确保电力传动系统的控制精度和可靠性。
二、PID自适应控制器
常规PID控制算法为：
(1) 
用求和代替积分，微分用有限差分代替，即上式为：
(2) 
式中T为采样周期，KP是比例系数，KI=KP/TI是积分比例系数，KD=KPTD是微分比例系数。
根据上式，组成由两层线性神经网络构造的控制器，如图1所示。它是由比例、积分、微分三个单元组成的一种动态前向网络，各层神经元个数、连接方式、连接权值是按PID控制规律的基本原则和已有的经验确定，能够保证系统的稳定和快速收敛。
图1神经网络PID自适应控制器
其中r为系统给定值，y为系统输出值，d为标定值， Lr为学习步长：0三、PLC控制系统的组成。
本文用PLC实现神经网络PID自适应控制，并应用于直流逻辑无环流可逆调速控制系统，使系统的控制精度达到了只有理论上才能实现的无静差。考虑到可逆调速控制系统的控制设备、器件数量多、对系统运行安全可靠提出的更高要求，采用高可靠性的PLC作为控制核心，以晶闸管为执行机构的直流调速控制系统，其系统主要由两部分构成，系统框图如图2所示。其中PLC实现神经网络PID自适应器与逻辑无环流双闭环的控制部分，长划线-点-点虚线框内为(V—M)三相桥式晶闸管—电动机系统，GT为V—M系统的晶闸管触发电路，它由硬件实现。短划线虚线框内为换向软开关，由PLC软件实现。
该系统为速度、电流双闭环调速系统，也就是说PLC对这三个模拟输入信号分别进行速度调节器和电流调节器相串联的两级PID运算，向晶闸管的触发电路给出移相电压信号。所以，系统跟随的快速性及控制精度关键取决于PID调节器的设计和调节精度。本系统采用单神经元组成的PID自适应控制器，它即具有传统PID控制器的优点，又具有神经网络的并行结构和学习记忆功能，并且结构简单，易于实现，所以它更适合于控制系统。
三、基于PLC的自适应控制方法
作为现代工业三大支柱(机器人、CAD/CAM、PLC)之一的PLC具有可靠性高、抗*力强、操作灵活简单、接线简洁、性价比高等优点，特别是易于扩展、编程简单、耐恶劣环境能力强等特点，已迅速占领了工业生产自动化领域，成为工业自动化领域的强有力工具。
在PLC中实现神经网络PID自适应控制，即可减少分接头数，提高PID调节的快速性和控制精度，又可以保证动作的可靠性，提高系统运行的安全性。
在直流双闭环调速系统中，为了提高系统响应的快速性和限流的必要性，电流内环仍然采用传统的PI调节器，而转速环则采用神经网络PID自适应控制器，以提高系统的鲁棒性。这两级相串联的PID运算都由PLC实现，我们把这一运算环节作为中断程序来处理。PLC的PID自适应控制中断处理子程序流程图如图3所示。
图3中断处理子程序流程图
我们选用西门子公司S7-200系列的PLC进行系统配置[5]。根据逻辑无环流可逆直流调速系统实际运行的要求，PLC主要实现了两级串联PID自适应调节及逻辑换向原则。同时，还实现了系统保护功能和系统显示功能。
针对该直流调速系统的控制功能，我们在实验室进行了带负载实际运行实验，实验直流电动机的额定参数为U =220V I = 12A n =1500转/分，实验线路示意图如图2所示。实测的机械特性数据如下表所示：
测试结果证实，其静特性能够达到只有理论上的无静差，静差率S = 0。
其它技术性能指标也均达到了设计要求。
