從事工控也有三年多了，一直都是用總線(xiàn)伺服，脈沖的早就忘掉
請教各位師傅，PLC發(fā)脈沖的最高頻率是多少，伺服驅動(dòng)器接收脈沖動(dòng)作又是怎么和PLC銜接的
比如我想伺服電機1秒轉完一圈，驅動(dòng)器分辨率是23位，8388608為一圈，
我看到一些主流PLC自帶發(fā)脈沖口的最高頻率為200KPPS，一秒200000個(gè)脈沖，發(fā)完8388608，也要41秒啊，那是怎么控制到1秒轉完一圈呢
不懂就要不恥下問(wèn)，讓各位師傅見(jiàn)笑了，也再次先謝謝各位師傅解答疑惑

一般都是設置伺服驅動(dòng)器里面的齒輪比，其實(shí)就是間接的把電機轉一圈所需的脈沖數等比例變少。
