描述

LUST–VF1410LHFS41

在电力拖动的发展历史中，交流与直流拖动两种方式始终并存于工业领域中。伴随着科学发展的进程，它们相互竞争，相互促进，推动电力拖动历史的发展。
    在19世纪80年代以前，利用蓄电池的直流拖动系统占统治地位。80年代后，随着三相交流电的传输方式的应用而产生笼型交流电动机，并很快在工业生产及人民生活的各个领域获得广泛的应用，并占据主要地位。之后，随着科技的发展，对拖动系统提出更高的要求，特别是在精密机械、冶金、国防工业等方面，要求调速精度高、调速范围宽、动态性能好，起制动灵活等，交流拖动则难以满足以上要求。因此，过去很长一段时期，在高性能的电力拖动系统中，一直是直流拖动占主要地位。然而交流电动机与直流电动机相比，也具有很多明显的优点。
    （1）交流电动机不存在换向器的转动速度限制，也不存在电枢元件的电抗电势限制，其转速可以设计得比相同功率的直流电动机转速更高。
    （2）直流电动机的电枢电流电压的值受换向器的限制，交流电动机则无此限制，它的单机功率可以比直流电动机更大。
    （3）直流电动机换向器制作工艺复杂、成本较高，相比之，交流电动机则成本低廉。
    （4）直流电动机高速运行时，由于受电抗电势的限制，一般最高速时（额定转速以上），输出功率仅能达到额定功率的80%，交流电动机则不受限制，它可以在高速时以额定功率运行。
    （5）交流电动机无换向器之类经常需要保养维护的部分。维护方便，经久耐用。在某些恶劣的环境下，例如，易燃易爆场合，也能可靠工作。
    （6）直流拖动系统的控制设备复杂、机构庞大、造价高。而某些简单的交流调速系统（特别是现在大量使用的变频器的调速系统）则具有设备简单、造价低、维护方便的优点。
    （7）现在大量使用的变频器调速系统在节能方面有明显的优势（特别是在风机、泵类方面的应用中）。
    由于交流拖动具有以上优点，过去在一些性能要求不高的场合，仍有人愿意采用交流电动机调速，以求得体积小、系统简单、维护方便的优点。近年来，随着电子计算机的发展及新型电力电子器件的出现，使交流变频器调速方式获得广泛应用，许多过去采用直流电动机的精密设备、大型设备，现在改用交流拖动的例子不胜枚举。目前已有逐渐取代直流拖动的趋势。

主营：本特利，英维思，伍德沃德，福克斯波罗、西屋、瑞恩、施耐德莫迪康、ABB、AB、西门子、摩托罗拉、GE发那科、安川、博世力士乐，ACSO，力士乐等各大品牌的DCS系统配件，机器人系统配件，大型伺服系统备件。

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。
