描述

6DS1703-8AB
变频器是把工频电源(50Hz或60Hz)变换成各种频率的交流电源,以实现电机的变速运行的设备,其中控制电路完成对主电路的控制,整流电路将交流电变换成直流电,直流中间电路对整流电路的输出进行平滑滤波,逆变电路将直流电再逆变成交流电。对于如矢量控制变频器这种需要大量运算的变频器来说,有时还需要一个进行转矩计算的CPU以及一些相应的电路。这是变频器修理中最变频器的定义。
变频器的分类方法有多种,按照主电路工作方式分类,可以分为电压型变频器和电流型变频器;按照开关方式分类,可以分为PAM控制变频器、PWM控制变频器和高载频PWM控制变频器;按照工作原理分类,可以分为V/f控制变频器、转差频率控制变频器和矢量控制变频器等;在变频器修理中,按照用途分类,可以分为通用变频器、高性能专用变频器、高频变频器、单相变频器和三相变频器等。
 在交流变频器中使用的非智能控制方式有V/f协调控制、转差频率控制、矢量控制、直接转矩控制等。V/f控制是为了得到理想的转矩-速度特性,基于在改变电源频率进行调速的同时,又要保证电动机的磁通不变的思想而提出的,通用型变频器基本上都采用这种控制方式。V/f控制变频器结构非常简单,但是这种变频器采用开环控制方式,不能达到较高的控制性能,而且,在低频时,必须进行转矩补偿,以改变低频转矩特性。在变频器修理中,转差频率控制是一种直接控制转矩的控制方式,它是在V/f控制的基础上,按照知道异步电动机的实际转速对应的电源频率,并根据希望得到的转矩来调节变频器的输出频率,就可以使电动机具有对应的输出转矩。矢量控制是通过矢量坐标电路控制电动机定子电流的大小和相位,以达到对电动机在d、q、0坐标轴系中的励磁电流和转矩电流分别进行控制,进而达到控制电动机转矩的目的。通过控制各矢量的作用顺序和时间以及零矢量的作用时间,又可以形成各种PWM波,达到各种不同的控制目的。直接转矩控制是利用空间矢量坐标的概念,在定子坐标系下分析交流电动机的数学模型,控制电动机的磁链和转矩,通过检测定子电阻来达到观测定子磁链的目的,因此省去了矢量控制等复杂的变换计算,系统直观、简洁,计算速度和精度都比矢量控制方式有所提高。
变频器主电路是给异步电动机提供调压调频电源的电力变换部分,变频器的主电路大体上可分为两类:电压型是将电压源的直流变换为交流的变频器,直流回路的滤波是电容。电流型是将电流源的直流变换为交流的变频器,其直流回路滤波是电感。 它由三部分构成,将工频电源变换为直流功率的“整流器”,吸收在变流器和逆变器产生的电压脉动的“平波回路”,以及将直流功率变换为交流功率的“逆变器”。

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....
