电气控制系统是整个设备的核心部分，设备的控制软件安装在MC运动控制器中。所有的控制指令运算工作输入输出信号系统状态监视，以及与操作人员的信息交流均由该部分完成。

The electrical control system is the core part of the entire equipment, and the control software of the equipment is installed in the MC motion controller. All control instruction calculations, input and output signal system status monitoring, as well as information exchange with operators, are completed by this section.

该系统采用松下支持RTEX总线的A6N伺服及电机。RTEX具有极高的性价比，采用RTEX总线控制系统后，客户在不增加电机成本的情况下，大幅降低了配线安装工作。100M的网络带宽和RTEX优异的稳定特性，确保了MC1002R与系统各个A6N伺服驱动器之间的控制周期能够达到0.5ms，从而大幅提高了客户机器的控制精度。

The system adopts Panasonic's A6N servo and motor that support RTEX bus. RTEX has a very high cost performance ratio. By adopting the RTEX bus control system, customers can significantly reduce wiring and installation work without increasing motor costs. The 100M network bandwidth and excellent stability characteristics of RTEX ensure that the control cycle between MC1002R and various A6N servo drivers in the system can reach 0.5ms, greatly improving the control accuracy of the customer's machine.

操作人员对设备的使用所需要的大量的数据输入，以及操作人员需要了解的设备运行的信息，均通过触摸屏来完成。

The large amount of data input required for the use of equipment by operators, as well as the information about the operation of the equipment that operators need to know, are all completed through the touch screen.

铝条折弯的工艺流程

The process flow of aluminum bar bending

设备上电后，通过触摸屏输入铝框图形参数，踩下脚踏开关设备开始运行，控制系统通过判断原料位置选择自动上料流程还是直接进入自动折弯流程，并自动判断当前原料的余料接头位置是否出现在禁折区。步进给料系统将由控制系统计算后的料长精确的给进折弯刀头，由折弯系统完成需要的折弯形状。

After the device is powered on, input the aluminum frame graphic parameters through the touch screen, press the foot switch, and the device starts running. The control system selects the automatic feeding process or directly enters the automatic bending process by judging the position of the raw materials, and automatically determines whether the position of the remaining material joints of the current raw materials is outside the prohibited folding area. The step feed material system will accurately feed the material length calculated by the control system to the bending blade, and the bending system will complete the required bending shape.

重复以上两步，直完成整个铝框成形流程。

Repeat the above two steps until the entire aluminum frame forming process is completed.

在铝框折弯过程中，随时会出现当前加工的铝条即将用完的情况，通过系统自动判断可使后续铝条自动续接当前铝条尾部，不中断当前铝条的成形工作。

During the bending process of the aluminum frame, there may be situations where the current processed aluminum bars are about to be used up. The system automatically determines that the subsequent aluminum bars can be automatically connected to the tail of the current aluminum bar without interrupting the forming work of the current aluminum bar.
