1-2: Electrical Principles

本机床电气控制系统是以PLC为核心，配以电器控制及液压控制，以实现机床各动作，主要操作按键均以操作台为主，左右侧辊、下辊同步数字控制必须在操作台操作状态下操作控制。各动作移动的数字通过触摸屏界面显示，便于直观操作，由于左右侧辊及下辊工作，翻倒架工作均以液压源为动力，动作前请先启动油泵电机。
The electrical control system of this machine tool is centered around the PLC, supplemented by electrical and hydraulic controls to achieve various machine tool operations. The main operation buttons are primarily on the control panel. The synchronized digital control of the left and right rollers and the lower roller must be operated in the control panel mode. The digital movement of each action is displayed on the touch screen interface for intuitive operation. Since the left and right rollers and the lower roller, as well as the tilting frame, are powered by a hydraulic source, please start the oil pump motor before operating.

Flip the current values of Yf on the side to be overturned and Yg on the fixed side. Whichever side's hydraulic cylinder digital display value is smaller, set the compensation value on that side in the compensation parameter display (compensate by how much it is smaller). After compensation is completed, the digital displays on both sides should be the same, and the compensation parameter setting is complete. It can also be automatically compensated by pressing the lower roller compensation button for 3 seconds.

卷制工件时显示各坐标的当前数值
Displaying the current values of each coordinate when winding workpieces

友情提醒：当左右辊、下辊的《Yf》和《Yg》后面的数字值（当前位置值）都分别等于《Yf翻倒侧》和《Yg固定侧》下面的数字值（当前设定值）时，操作左右辊上升、下辊上升按钮将无效，因为系统不但能实现同步升降功能，而且还能实现上升预置定位功能。如工作需要再次上升运行，请同时按动《自动停止》和需要操作的上升按钮，将再次上升运行（但是这时候同步、定位功能将不运行）。
Friendly reminder: When the numerical values (current position values) after 《Yf》 and 《Yg》 of the left and right rolls and lower roll are respectively equal to the numerical values (current setting values) below 《Yf flip side》 and 《Yg fixed side》, pressing the buttons to raise the left and right rolls and lower roll will be ineffective, because the system not only achieves the synchronous lifting function but also achieves the rise preset positioning function. If the work requires another run-up operation, please press the 《Auto Stop》 and the required rise button simultaneously to perform another run-up operation (but at this time, the synchronous and positioning functions will not operate).

当卷制完工件后，需取出工件，将下辊下降至最下位，此时“下辊下位”指示灯亮，这时候按“翻倒架翻倒”让翻倒架翻倒至水平位，或由限位开关自动停止，便于取出工件；取出工件后，按“翻倒架复位”使翻倒架充分复位，同时“翻倒架复位” 指示灯亮，当完成所有工件后，关闭油泵，电柜右侧断路器总电源开关拨于“OFF”位，切断总电源。
After winding the finished workpiece, remove the workpiece, lower the lower roll to the lowest position, and at this time, the "Lower Roll Low Position" indicator light will turn on. At this point, press "Flip Frame Flip" to make the flip frame flip to the horizontal position, or stop automatically by the limit switch, to facilitate the removal of the workpiece; after removing the workpiece, press "Flip Frame Reset" to fully reset the flip frame, and at the same time, the "Flip Frame Reset" indicator light will turn on. When all workpieces are completed, turn off the oil pump, and turn the total power supply switch on the right side of the electrical cabinet to the "OFF" position to cut off the total power.

*******特别友情关注：卷制完工件后如需在卷板机上焊接工件，请务必将电焊机焊接地线直接良好接触在卷制工件上。绝不允许以卷板机体作过渡焊接地线，以免大电流冲击损坏位移传感器和PLC及触摸屏数显仪表。********
*******Special Friendly Attention: If you need to weld the workpiece on the rolling machine after winding the finished workpiece, please be sure to directly and well contact the welding ground wire of the electric welding machine on the wound workpiece. It is strictly forbidden to use the rolling machine body as a transitional welding ground wire to avoid damage to the displacement sensor, PLC, and touch screen digital display instrument due to high current impact.********
