西门子840D数控系统调试

1、上电之前的准备 一：将NCK主板卸下，检查NCK主板上的电池是否正确安装。 正确安装之后将NCK主板安装到NCU盒上。二：外围线路的连接A (1)每根轴的动力线，编码器反馈线是否正确安装(X411 轴 1编码器，X422轴2编码器，动力线插口 X轴对应A1 口，Z 轴对应 A2 口，2AXIS)A (2)设备总线，直流母线等是否正确可靠连接。A (3) 3相电源进线连接是否可靠，U,V,W是否对应。A (4) SIMATIC 线的连接(IM361 接 OUT 口，NCK 接 X111 口)A (5) MPI线的连接(两头ON中间OFF)A (6) MCP面板的节地址开关设置(810D面板的节地

2、址为14, 机床控制面板后面的S3开关(1-8)依次设为OFF OFF ON ON ON ON OFF OFF;840D面板的节地址为6，机床控制面板后 面的S3开关从左到右依次设为ON OFF ON OFF ON ON OFF OFF)A (7)如果是PCU50，要将显示器后面的硬盘开关拨到ON的 位置。上电之后先安装HMI软件。软件拷贝到E盘三：上电A (1)上电之前请将数控系统的热控断开，MCP和OPI面板上 的24V电源拔掉，以免由于接线错误造成器件烧坏。A (2)上电之后检查供给数控系统的电压是否为380V，MCP和OPI面板的电源是否为直流24V,且正负极性正确。(3)如果2正确，

3、断电，合上热控，MCP和OPI面板的直流 电源插上，上电调试。四：PLC，NC总清1、NC总清步骤：(1)将NC启动开关S3f“1”：(2)启动NC,如NC已启动，按复位按钮S1：(3)待NC启动成功，七段显示器显示“6”或者“b”，将S3f “0”；这时H1 (左列)显示灯“+5V”显示绿灯，NC总清执行完成。即：将S3置于1位置后，按下复位按钮S1,待七段码管显示“6” 或者“b”后，将S3置于0位置。NC总清后，SRAM内存中的内 容被全部清掉，所有机器数据被预置为缺省值。2、PLC总清步骤：(1)将PLC启动开关S4f“2”=PS灯会亮。(2)S4-“3”并保持等到PS灯再次亮=PS灯

4、灭了又再亮。(3)在3秒之内，快速地执行下述操作S4： “2”一“3”一“2”：=PS灯先闪，后又亮，PS灯亮。(有时PS灯不亮)等PS和PF灯亮了，S4-“0”:=PS和PF灯灭，而PR灯 亮。即：将S4按钮“2-3-2-3-2-0”；或者打开任意一个PLC 程序，通过PLC-Clear/Rest来实现。PLC总清后，PLC程序可 通过STEP7软件下传至系统。如PLC总清后屏幕上有报警可作一次NCK复位（热启动）。五：配轴1、设置密码Startup f Passwordf Set Password f SUNRISE fOK2、R参数扩展MD28050:通道R专用参数。通常扩展为900MD
