我有一台FX3U的PLC 和一个欧姆龙的旋转编码器，现要求伺服电机送3次料，第一固定送4公分，第二次送D0公分，第三次送D1公分，D0和D1分别是自己设定值
哪么程序是否是下面这样的   问题重点在于高速计数器和编码器的接线方式

out c237 d5                                                                                                                                                                                                           有编码器A B Z   相相                                                                                                                                                                                                                              的接线方式
是不是3次送料需要3个不同的高速计数器，能不能只用1个，如C235只用这一个计数器，
但是只用这一个的话又会造成双线圈输出，求高手指点

如果精度要求不算万分严格的，是否考虑不需要编码器，只用伺服电机？

小弟没做过类似项目纯属建议

这个真不是问题,台果你稍微懂一点电子的话
如果这都不懂就不要编程了,机械这东西关系到人命的

你这不就是走三段距离吗，简单的问题搞得太复杂，有点画蛇沃足。

欧姆龙的编码器一般是6线的，+24V 0V A B Z A接X0 B 接X1  编程时用C251就行了
如果编码器输出的是差分+24v 0v A+ A- B+ B- Z+ Z-就要用TTL转HTL转换器

编码器一圈的脉冲就是伺服一圈的脉冲，将距离换算成脉冲量
定位用DDRVA D100 K1000 Y0 Y1
如将4公分换算成脉冲量是 10000存到D20    D0距离换算成脉冲量是2000存到D22    D1的距离转换成脉冲量存到 d24
定位数据传送条件  ld m0 dmov d20 d100
                                  ld m1  dmov  d22  d100
                                  ld m2   dmov   d24    d100
定位启动       ld m10  DDRVA D100 K1000 Y0 Y1                k1000是频率自己改

用一个高速计数器计编码器的脉冲数，再用比较指令即可，不用搞3个高速计数器

我不懂！！学习

又不是高精度要求，既然用了伺服又何必加编码器，画蛇添足了
