西門(mén)子G120變頻器 (CU2xx-2): 實(shí)現(xiàn)轉(zhuǎn)矩限制下的速度控制
描述
在一些應(yīng)用中，例如皮帶傳動(dòng)，當(dāng)起動(dòng)和制動(dòng)的時(shí)候通常需要限制力矩以防止電機(jī)堵轉(zhuǎn)或皮帶滑動(dòng)。
問(wèn)
如何在電機(jī)加速和制動(dòng)的時(shí)候限制力矩？
答
該功能可以通過(guò)自由功能塊（FFB）來(lái)實(shí)現(xiàn)。這個(gè)實(shí)例展示了在有編碼器的矢量閉環(huán)（只針對(duì)CU250S-2）或無(wú)編碼器的矢量閉環(huán)控制下如何通過(guò)轉(zhuǎn)矩限幅限制轉(zhuǎn)矩輸出。假定的速度監(jiān)控值是300轉(zhuǎn)每分。當(dāng)轉(zhuǎn)速低于300轉(zhuǎn)每分時(shí)轉(zhuǎn)矩限制在40%。當(dāng)轉(zhuǎn)速高于300轉(zhuǎn)每分時(shí)轉(zhuǎn)矩限制在100%。
注意
這個(gè)常問(wèn)問(wèn)題對(duì)于配備CU2xx-2控制單元（固件版本4.x）的SINAMICS G120 / G120D / G120P變頻器是有效的。
* 該常問(wèn)問(wèn)題既不講解如何調(diào)試系統(tǒng)也不講解如何設(shè)置和優(yōu)化矢量控制

如何給SINAMICS G120變頻器連接直流24V外部供電？
問(wèn)題:
如何給SINAMICS G120變頻器連接直流24V外部供電?
答案：
當(dāng)斷開(kāi)主回路電源時(shí)，又希望保持SINAMICS G120變頻器的控制電源，就需要給變頻器連接直流24V外部供電。根據(jù)變頻器功
率單元的不同，有兩種連接方式。
（1）當(dāng)功率單元的外形尺寸為FSA ～ FSF時(shí)，直流24V供電需要連接到控制單元的31/32號(hào)端子上。如下圖：
（2）當(dāng)功率單元的外形尺寸為FSGX時(shí)，直流24V供電要連接到功率單元X9端子排的1/2號(hào)端子上，無(wú)需連接到控制單元。
X9端子排位置以及1/2號(hào)端子說(shuō)明如下：
