应用LOGO!解决烘呢机风扇步进启动方案

Stepping startup programs on using LOGO! solve the woollen cloth dyeing machine's

应用西门子LOGO!通用逻辑控制器编程对意大利ROSL16/1800多层拉幅烘呢机风机的启动程序进行设计改造,用新程序直接取代原机械电动式启动程序,而无需改变原有的电气线路,只要将编制好程序的LOGO!进行正确的外部连线,使得改造工作简单易行,从而极大地提高了设备的运行可靠性和寿命。由于LOGO!内具有很多通用模块和特殊模块功能,编程后可替代定时器、继电器、时钟、接触器等所实现的功能,从而使复杂繁琐的"继电器—接触器"控制线路变得简单成为可能。

To put in use SIEMENS LOGO! univesal logic lontfor module＇s programming for italian multllayer drying and thermo-fixing stenter ROSL16/1800＇s starup problems to design transformation, using new problems directly replace starup problems that original way of machinery electrical, do not change the original electric lines, just to do correct external connection using LOGO! which procedures for the preparation of good, let the transformation become easy; thus greatly improve reliability and life of equipment running. As a result of LOGO! In has very many general modules and the special module function, may substitute the function after the programming which many timers, the relay, the clock, the contact device, the relay realize, therefore will be complex tediously ＂the relay - contact device＂ to control the line to become becomes extremely simply possibly.
