电力拖动方案选择是电气控制系统设计的主要内容之一，也是以后各部分设计内容的基础和先决条件。什么是电力拖动方案呢？所谓电力拖动方案是指根据零件加工精度、加工效率要求、生产机械的结构、运动部件的数量、运动要求、负载性质、调速要求以及投资额等条件去确定电动机的类型、数量、传动方式以及拟订电动机起动、运行、调速、转向、制动等控制要求
变频器工作原理弄明白之前，不妨先看看变频器究竟为何方神圣？
同一种电器一般用相同的字母表示，但在字母的后边加上数码或其他字母下标以示区别，例如两个接触器分别用KM1、KM2表示，或用KMF、KMR表示。全部触头都按常态给出。对接触器和各种继电器，常态是指未通电时的状态；对按钮、行程开关等，则是指未受外力作用时的状态。原理图中，无论是主电路还是辅助电路，各电气元件一般按动作顺序从上到下，从左到右依次排列，可水平布置或者垂直布置。原理图中，有直接电联系的交叉导线连接点，要用黑圆点表示。无直接联系的交叉导线连接点不画黑圆点。

操作频率接触器在吸合瞬间，吸引线圈需消耗比额定电流大5～7倍的电流，如果操作频率过高，则会使线圈严重发热，直接影响接触器的正常使用。为此，规定了接触器的允许操作频率，一般为每小时允许操作次数的最大值
PLC、工控机和现场总线为工业自动化提供了很好的底层控制硬件基础。随着软件技术的迅猛发展，控制软件不再是单调的数字和菜单操作界面，而是图形化的人机交互工具。好的工控软件包括了从底层的数据采集、数据库、控制逻辑运算到高层的人机图形界面(MMI)。
