摘要:详细分析箔绕机的系统说明

 箔绕机系统要求变频器采用单动/联动的状态,而且在联动时还需要采用正常收卷的状态和褪绕的状态,所以系统采用PLC控制,这样可以简化外部电路,减少故障点,便于维护和改变工作状态。所有的这些工作状态的转换通过转换开关,输入PLC,经过PLC的程序,输出相应的工作状态,控制相应的变频器工作。

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.

收卷变频器,由于其只是要求采用开环的速度控制,系统速度有外部模拟量调整,而工作状态有PLC控制,所以其控制方式比较简单,针对急停等功能需要配备制动单元(可以变频器内置)制动电阻等。

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.).

放卷变频器要求能实现恒张力控制,根据客户需要采用转矩控制方式,但是系统要求在闭环矢量方式中运行,所以需要配备编码器,PG卡等,而且根据其工作状态其始终使用在制动状态(即发电状态),所以需要配备制动电阻,制动单元标准内置,其转矩控制功能有变频器实现。

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.
