一、原点回归指令
一、停止指令
在一般的STOP动作（减速停止）中，使用[指令的OFF]或者[正转极限标志位和反转极限标志位]。

在为了避免危险而要求立即停止的场合，请使用脉冲停止标志位。

但是，如果在定位指令的执行过程中将脉冲输出停止标志位置ON，那么脉冲输出立即停止。

因此有电机立即停止、设备损坏的危险。

二、指令执行结束标志位、指令执行异常结束标志位
三、FNC157-PLSV可变速脉冲输出
执行PLSV指令一次，则D1中脉冲量以S1的频率从D2输出。

例子：
成组位软元件的传送：
例子：
四、四则逻辑运算
DIV除法指令是将S1制定的常数或源元件中的二进制数作为被除数，除以S2指定的常数或源元件中的二进制除数，商送到指定的目标元件D 中去，榆树送到目标元件D+1 的元件中。

OUT指令用于T和C，其后须跟常数K，K为延时时间或计数次数。

常数K的设定，如下：定时器、计数器K的设定范围实际的设定值步数1ms定时器1~32,7670.001~32.767秒310ms定时器1~32,7670.01~327.67秒3100ms定时器0.1~3276.7秒16位计数器1~32,767同左332位计数器-2,147,483,648~+2,147,483,647同左5双线圈输出在用户程序中，同一个编程元件的线圈使用了两次或多次，称为双线圈输出。

本文是FX3U用户编程手册的基本应用指令说明书，旨在帮助用户更好地理解和使用FX3U PLC。

以下是对各个指令进行详细说明。

1. LD指令：LD指令用于将数据从指定的地址加载到寄存器中。

它的基本语法为LD A, B，其中A表示目标寄存器，B表示源地址。

例如，LD D100, M10将把M10地址处的数据加载到D100寄存器中。

2. AND指令：AND指令用于执行逻辑与操作。

它的基本语法为AND A, B，其中A和B可以是寄存器或地址。

例如，AND Y0, X1将执行Y0寄存器与X1寄存器的逻辑与操作。

3. OR指令：OR指令用于执行逻辑或操作。

它的基本语法为OR A, B，其中A和B可以是寄存器或地址。

例如，OR Y0, X1将执行Y0寄存器与X1寄存器的逻辑或操作。

4. OUT指令：OUT指令用于将数据从寄存器输出到指定的地址。

它的基本语法为OUT A, B，其中A表示源寄存器，B表示目标地址。

例如，OUT D100, Y0将把D100寄存器中的数据输出到Y0地址处。

5. IN指令：IN指令用于从外部设备（如传感器）读取数据并保存到寄存器中。

它的基本语法为IN A, B，其中A表示目标寄存器，B表示外部设备的地址。

例如，IN D100, X0将从X0地址处读取数据并保存到D100寄存器中。

6. TIM指令：TIM指令用于设定定时器的时间间隔。

它的基本语法为TIM A, B，其中A表示定时器的编号，B表示时间间隔。

例如，TIM T0, 100将设置T0定时器的时间间隔为100毫秒。

7. CMP指令：CMP指令用于比较两个数据的大小。

它的基本语法为CMP A, B，其中A和B可以是寄存器或地址。

例如，CMP D100,D200将比较D100和D200寄存器中的数据大小。
