我有一臺FX3U的PLC 和一個歐姆龍的旋轉編碼器，現要求伺服電機送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分別是自己設定值
哪么程序是否是下面這樣的   問題重點在于高速計數器和編碼器的接線方式

ld x3                                                                                                                                                                                                               .
mul d1 k1024(脈沖數) d5       第三次送料                                                                                                                                out c235 d5    能否想這樣寫 求指教，還
out c237 d5                                                                                                                                                                                                           有編碼器A B Z   相相                                                                                                                                                                                                                              的接線方式
是不是3次送料需要3個不同的高速計數器，能不能只用1個，如C235只用這一個計數器，
但是只用這一個的話又會造成雙線圈輸出，求高手指點

如果精度要求不算萬分嚴格的，是否考慮不需要編碼器，只用伺服電機？

小弟沒做過類似項目純屬建議

這個真不是問題,臺果你稍微懂一點電子的話
如果這都不懂就不要編程了,機械這東西關系到人命的

你這不就是走三段距離嗎，簡單的問題搞得太復雜，有點畫蛇沃足。

歐姆龍的編碼器一般是6線的，+24V 0V A B Z A接X0 B 接X1  編程時用C251就行了
如果編碼器輸出的是差分+24v 0v A+ A- B+ B- Z+ Z-就要用TTL轉HTL轉換器

編碼器一圈的脈沖就是伺服一圈的脈沖，將距離換算成脈沖量
定位用DDRVA D100 K1000 Y0 Y1
如將4公分換算成脈沖量是 10000存到D20    D0距離換算成脈沖量是2000存到D22    D1的距離轉換成脈沖量存到 d24
定位數據傳送條件  ld m0 dmov d20 d100
                                  ld m1  dmov  d22  d100
                                  ld m2   dmov   d24    d100
定位啟動       ld m10  DDRVA D100 K1000 Y0 Y1                k1000是頻率自己改

用一個高速計數器計編碼器的脈沖數，再用比較指令即可，不用搞3個高速計數器

我不懂�。�學習

又不是高精度要求，既然用了伺服又何必加編碼器，畫蛇添足了
