注:
SIMODRIVE Sensor/Motion Connect 500 具有增量式編碼器的作用,它帶有預(yù)安裝電纜,用于計(jì)數(shù)和定位功能。
FM 350-1是智能型單通道計(jì)數(shù)模塊,用于實(shí)現(xiàn)各種基本的計(jì)數(shù)任務(wù)。它可以用在 SIMATIC S7-300 和 ET 200 M 中(以S7-300/-400為主站)。
應(yīng)用包括:
該模板提供編碼器電源。
該模塊具有如下機(jī)械特性:
組態(tài)軟件包
組態(tài)所需的組態(tài)軟件包包括:
FM 350-1通過下列方法減輕CPU的負(fù)擔(dān):
功能如下:
標(biāo)準(zhǔn)功能塊 |
|
---|---|
CNT_CTRL (FC 0) |
用于控制 FM 350-1 的計(jì)數(shù)器 |
DIAG_INF (FC 1) |
用于提供 FM 350-1 的診斷信息 |
運(yùn)行模式
在直接可連接的門控信號控制下,F(xiàn)M 350-1 計(jì)數(shù)器能夠按照最高 500 kHz 的頻率檢測增量編碼器所發(fā)的脈沖。
工作模式 |
|
---|---|
連續(xù)計(jì)數(shù) |
門開啟后,從起始值起,在上下兩個(gè)極限值之間不停地計(jì)數(shù)。 |
單次計(jì)數(shù) |
門開啟后,根據(jù)主計(jì)數(shù)方向,系統(tǒng)從起始值起就一直進(jìn)行增計(jì)數(shù)或減計(jì)數(shù)。 |
|
|
|
|
周期計(jì)數(shù) |
門開啟后,從起始值開始,根據(jù)主計(jì)數(shù)方向,在編程好的范圍內(nèi)循環(huán)計(jì)數(shù)。 |
|
|
|
參數(shù)
在參數(shù)化屏幕格式的幫助下,用STEP 7進(jìn)行參數(shù)賦值。為此,需要一個(gè)組態(tài)包。
