機(jī)床回零操作是操作者操作機(jī)床時(shí)最常見(jiàn)的操作流程。對(duì)于配置增量編碼器的機(jī)床,機(jī)床回零,實(shí)際上是增量編碼器通過(guò)先碰撞擋塊,再尋找編碼器零點(diǎn)的過(guò)程,它的回零包含軸回到機(jī)床零點(diǎn)位置和定義機(jī)床零點(diǎn)位置兩層含義。由于絕對(duì)值編碼器和增量編碼器的原理不一樣,西門子絕對(duì)值編碼器調(diào)試完成后,已經(jīng)定義了機(jī)床和編碼器的零點(diǎn)位置,且定義好的零點(diǎn)不會(huì)因?yàn)閿嚯娤В话闱闆r下,就不需要再進(jìn)行回零的操作,所以絕對(duì)值編碼器所謂的“回零”只有軸回到機(jī)床零點(diǎn)位置這一層含義。
對(duì)于有些機(jī)床,增量編碼器的軸和絕對(duì)值編碼器的軸都有,客戶操作機(jī)床回零時(shí),習(xí)慣于按回零鍵讓各個(gè)軸回零,包括絕對(duì)值編碼器的軸。本文重點(diǎn)說(shuō)明一下,絕對(duì)值編碼器的“回零操作”設(shè)置,即類似于增量編碼器回零的手動(dòng)操作過(guò)程如何實(shí)現(xiàn)。一般分為兩種情況:
1. 系統(tǒng)回零界面,客戶手動(dòng)逐一按各軸正向回零鍵回零。
此時(shí),對(duì)于配有絕對(duì)值編碼器的軸,可設(shè)置其軸參數(shù)34330為0即可,無(wú)需更改PLC設(shè)置,軸可以手動(dòng)按正向回零鍵回零。
2. 系統(tǒng)回零界面,客戶按NC啟動(dòng)鍵各軸自動(dòng)回零。
此時(shí),對(duì)于配有絕對(duì)值編碼器的軸,除了設(shè)置其軸參數(shù)34330為0, 還需要將11300設(shè)置為0,然后在PLC中添加如下程序段(以828D為例),通過(guò)參數(shù)MD34110[Z]=1,MD34110[X]=2,MD34110[Y]=3 可設(shè)置回零順序。在參考點(diǎn)模式下,按循環(huán)啟動(dòng)鍵,軸就可以自動(dòng)回零。
