变频器控制方式特点:
其特点是控制电路结构简单、成本较低,机械特性硬度也较好,能够满足一般传动的平滑调速要求,已在产业的各个域得到广泛应用。但是,这种控制方式在低频时,由于输出电压较低,转矩受定子电阻压降的影响比较显著,使输出大转矩减小。另外,其机械特性终究没有直流电动机硬,动态转矩能力和静态调速性能都还不尽如人意,且系统性能不高、控制曲线会随负载的变化而变化,转矩响应慢、电机转矩利用率不高,低速时因定子电阻和逆变器死区效应的存在而性能下降,稳定性变差等。因此人们又研究出矢量控制变频调速。
S7-1200通信和程序的特点:
S7-1200是西门子的新一代的控制器,在串口通信方面在硬件与软件方面都与S7-200不同:通讯方面:作为200的升产品,1200不支持DP等应用比较广泛的通讯协议,但保留了强大的自由口通讯功能;程序方面:引入块概念,更接近于300,编程方便,尤其是通讯方面的编程(自由口、MODBUS等,一个块可以控制多个驱动器,不同电机的数据存储在不同的数据库中;硬件方面:S7-1200现有的几款PLC都可以扩展3个串口通信模板(即可以全部是RS232接口,也可以全部是RS485接口,也可以是两种接口的组合),而S7-200这不可以进行扩展,只能用本体上的RS485口,在这一点上功能强了。软件方面:S7-1200,在编程上与S7-300的编程方法类似,组态完硬件接口,直接调用功能块就可以,非常简单,不像S7-200需要对SM进行操作。S7-1200与S7-300在串口通信比较起来基本上一样,但在作Modbus的通信时不需要额外的Dongle来支持。
