                詳細分析箔繞機的系統說明

                箔繞機系統要求變頻器采用單動/聯動的狀態,而且在聯動時還需要采用正常收卷的狀態和褪繞的狀態,所以系統采用PLC控制,這樣可以簡化外部電路,減少故障點,便于維護和改變工作狀態。所有的這些工作狀態的轉換通過轉換開關,輸入PLC,經過PLC的程序,輸出相應的工作狀態,控制相應的變頻器工作。

                Foil winding machine system requirements inverter adopts single action / linkage of the state, but also in the linkage also need to use normal rolling state and faded around the state, so the system is controlled by PLC, which can simplify the external circuit, low failure rate, convenient maintenance and change the working state. Conversion of all these work state of the switch, the input PLC, through the PLC program, the output of the corresponding working condition, the corresponding control frequency converter.

                收卷變頻器,由于其只是要求采用開環的速度控制,系統速度有外部模擬量調整,而工作狀態有PLC控制,所以其控制方式比較簡單,針對急停等功能需要配備制動單元(可以變頻器內置)制動電阻等。

                Coiling frequency converter, due to its only require the use of open loop speed control, speed adjustment system with external analog, and the working state of PLC control, the control is relatively simple, for emergency stop functions need to be equipped with a brake unit (can be built in the inverter braking resistance etc.).

                放卷變頻器要求能實現恒張力控制,根據客戶需要采用轉矩控制方式,但是系統要求在閉環矢量方式中運行,所以需要配備編碼器,PG卡等,而且根據其工作狀態其始終使用在制動狀態(即發電狀態),所以需要配備制動電阻,制動單元標準內置,其轉矩控制功能有變頻器實現。

                Unreeling inverter to realize the constant tension control, according to the need of using torque control mode of the customer, but the system requirements to run in a closed loop vector method, so need to be equipped with encoder, PG card, and according to its working state is always used in brake state (i.e. power state), so need to be equipped with a braking resistor, braking unit standards the built-in function, the torque control inverter.
