EL7211 | Servomotor terminal for resolver, 50 V DC, 4.5 A_RMS

The EL7211 servomotor EtherCAT Terminal with integrated resolver interface offers high servo performance in a very compact design for motors from the AM8100 and AM3100 series up to 4.5 A_RMS. The fast control technology, based on field-orientated current and PI speed control, supports fast and highly dynamic positioning tasks.

Monitoring of numerous parameters, such as overvoltage and undervoltage, overcurrent, terminal temperature or motor load via the calculation of a I²T model, offers maximum operational reliability. EtherCAT, as a high-performance system communication, and CAN-over-EtherCAT (CoE), as the application layer, enable ideal interfacing with PC-based control technology. The latest power semiconductors guarantee minimum power loss and enable feedback into the DC link when braking. 16 LEDs indicate status, warning and error messages as well as possibly active limitations.

公司總部下屬研發(fā)部、生產(chǎn)部、行政部、銷售部、市場部、支持與服務(wù)部。隨著公司的迅速發(fā)展，我們分別在奧地利、比利時(shí)、丹麥、芬蘭、法國、意大利、立陶宛、波蘭、俄羅斯、西班牙、瑞典、瑞士以及澳大利亞、巴西、中國、加拿大、南非、美國設(shè)立有分公司，加上世界各地的合作伙伴，Beckhoff 公司的業(yè)務(wù)已遍及 60 多個(gè)國家。

自 1980 年公司成立以來，Beckhoff 始終堅(jiān)持基于 PC 的控制技術(shù)，研發(fā)了大量的創(chuàng)新產(chǎn)品和解決方案，這正是 Beckhoff 得以持續(xù)發(fā)展的原因所在。如今，Beckhoff 早期提出的概念業(yè)已成為許多自動(dòng)化技術(shù)的標(biāo)準(zhǔn)，且被成功引入市場。Beckhoff 基于 PC 控制技術(shù)的理念和 Lightbus 系統(tǒng)、總線端子模塊以及 TwinCAT 自動(dòng)化軟件的推出，在自動(dòng)化技術(shù)領(lǐng)域有著里程碑式的歷史意義，在傳統(tǒng)控制行業(yè)，這些產(chǎn)品已被視作為高性能的解決方案，從而被廣泛接受。EtherCAT - 實(shí)時(shí)以太網(wǎng)解決方案 - 是一種具有前瞻性的技術(shù)，是前沿控制理念的新生代產(chǎn)物。
