plc控制柜與變頻控制柜有哪些區別？

在PLC和變頻器一起運用的自控系統中，應該側重留心以下事項：

In the automatic control system of PLC and inverter, the following items should be paid attention to

1、PLC供電電源與動(dòng)力系統電源(變頻器電源)分別配備，且PLC的供電應該選擇阻隔變壓器;

1. PLC power supply and power system power supply (inverter power supply) are equipped respectively, and the power supply of PLC should select the blocking transformer;

2、動(dòng)力線(xiàn)盡量與信號線(xiàn)分隔，信號線(xiàn)要做屏蔽;

2. The power line shall be separated from the signal line as far as possible, and the signal line shall be shielded;

3、無(wú)論是模擬信號輸入仍是模擬信號輸出，模擬量通道一概運用信號阻隔模塊;

3. Whether it is analog signal input or analog signal output, analog channel uses signal blocking module;

4、PLC程序里做軟件濾波規劃;

4. PLC program to do software filtering planning;

5、信號地與動(dòng)力地分隔規劃。plc控制柜廠(chǎng)家用來(lái)邏輯操控,首要用于組織的動(dòng)作流程操控；

5. Signal ground and power ground are planned separately. PLC control cabinet manufacturers are used for logic control, mainly for the organization of the action process control;

現在在自動(dòng)化操控系統中，低壓配電柜供貨商變頻器的運用也越來(lái)越廣，作為電力設備集成商，祥科的工程師經(jīng)常將變頻器與PLC集成在同一或相鄰的柜內，電機發(fā)起操控箱這樣會(huì )導致變頻器對PLC模擬量煩擾而形成收集數據的不穩定或呈現其他缺點(diǎn)。

Now in the automatic control system, the frequency converter of low-voltage distribution cabinet supplier is more and more widely used. As a professional integrator of power equipment, engineers of Xiangke often integrate the frequency converter and PLC in the same or adjacent cabinet, and the motor initiates the control box, which will cause the frequency converter to disturb the PLC analog quantity and form the instability of data collection or other shortcomings.
