描述

3BHB016295R0001

在工业自动化控制系统中,最为常见的是PLC和变频器的组合应用,并且产生了多种多样的PLC控制变频器的方法,其中采用RS-485通讯方式实施控制的方案得到广泛的应用:因为它抗干扰能力强、传输速率高、传输距离远且造价低廉。但是,RS-485的通讯必须解决数据编码、求取校验和、成帧、发送数据、接收数据的奇偶校验、超时处理和出错重发等一系列技术问题,一条简单的变频器操作指令,有时要编写数十条PLC梯形图指令才能实现,编程工作量大而且繁琐,令设计者望而生畏。本文介绍一种非常简便的三菱FX系列PLC通讯方式控制变频器的方法:它只需在PLC主机上安装一块RS-485通讯板或挂接一块RS-485通讯模块; 在PLC的面板下嵌入一块造价仅仅数百元的“功能扩展存储盒”,编写4条极其简单的PLC梯形图指令,即可实现8台变频器参数的读取、写入、各种运行的监视和控制,通讯距离可达50m或500m。这种方法非常简捷便利,极易掌握。本文以三菱产品为范例,将这种“采用扩展存储器通讯控制变频器”的简便方法作一简单介绍。PLC(MR型或MT型)的输出点、COM点直接与变频器的STF(正转启动)、RH(高速)、RM(中速)、RL(低速)、输入端SG等端口分别相连。PLC可以通过程序控制变频器的启动、停止、复位; 也可以控制变频器高速、中速、低速端子的不同组合实现多段速度运行。但是,因为它是采用开关量来实施控制的,其调速曲线不是一条连续平滑的曲线,也无法实现精细的速度调节。这种开关量控制方法,其调速精度无法与采用扩展存储器通讯控制的相比。1台PLC和不多于8台变频器组成的交流变频传动系统是常见的小型工业自动化系统,广泛地应用在小型造纸生产线、单面瓦楞纸板机械、塑料薄膜生产线、印染煮漂机械、活套式金属拉丝机等各个工业领域。采用简便控制方法,可以使工程方案拥有通讯控制的诸多优势,又可省却RS-485数据通讯中的诸多繁杂计算,使工程质量和工作效率得到极大的提高。但是,这种简便方法也有其缺陷:它只能控制变频器而不能控制其它器件;此外,控制变频器的数量也受到了限制。

先介绍几点经验。
1、先通读一遍“系统手册”(不管能不能看懂,先了解个大概,以便学习编程时查找);
2、由位控逻辑入手,逐渐增加定时、计数等条件,把或、与、非关系理顺;
3、进而练习整数运算、实数运算、类型转换;
4、量程转换、PID调节回路的建立及P、I、D参数的理解(最好是有个物理回路验证,比如变频器+电机+测速传感器);
5、循环、顺序、跳转等程序控制(尽量避免跳转,非跳不可时也是跳的越近越好);
6、中断、通讯、位置控制....

本人以ABB工业机器人配件DSQC系列和Motorola MVME系列,GE 卡件 模块 驱动器系列为主攻。各位电工朋友可根据自己的条件选择适合自己的PLC品牌,由于PLC的基本框架大同小异,学会一种至于其它的学习起来也就简单了。
