電機為交流異步電機，紙機設計最高轉速為1800m/min,傳動控制系統為TMdrive-10e2，PWM控制的交直交變頻矢量控制系統，功率元件采用絕緣柵雙極晶體管(IGBT)。
傳動逆變器柜類型較多，250KVA以下為抽屜式，250KVA以上為柜式結構，根據電機容量的差異來選用不同容量控制系統，用于紙機的變頻控制。
逆變器的傳動矢量控制組成：速度給定環節、速度調節器、D/Q軸電流調節器、磁通調節器、電壓調節器、PWM控制器等組成。主板在矢量控制系統完成IGBT觸發信號后，把觸發脈沖傳送到逆變器，控制IGBT導通和關斷，得到所需電機近似于正弦波的輸入電壓和頻率，進而調節電機轉速。
2.4 數據通信
傳動系統和PLC間通信采用FL-NET總線,光纖連接，變頻器與HUB之間，以太網通訊。結構仍以圖2為例。
PLC系統配置了一塊FL612接口模塊和一塊EGD模塊，與各變頻器進行數據交換。各變頻器地址均在EGD中配置，傳動與PLC的通信及傳動與傳動之間的通信都是通過EGD來完成數據交換的。
FL-NET網絡以Ethernet為物理層，采用總線拓撲結構，是日本采納的一種PLC網絡標準，其協議棧高層為UDP/IP+ UDP/IP+獨自循環通信協議，保證了通信的實時性。
完成PLC系統與傳動系統間數據交換基于EGD(Ethernet Global Data)以太網全局數據處理通信，EGD協議是美國GE自動化公司基于以太網技術的數據交換協議，它以數據報文形式在一個發送者和多個發送者之間實現100Mbps數據高速傳送，遵循UDP/IP獨自循環通信協議。數據發送時間間隔短，安全性強，不易丟失，各站為雙向角色，既是服務器也是客戶端。
3. 系統控制功能
TMEIC集成控制器完成整個紙機的速度計算與控制、負荷分配計算與控制、電機同步計算與保護等功能。
衛生紙機的速度基準以烘缸Yankee為準，Yankee烘缸由兩臺電機驅動，1#Yankee電機為master，控制方式為速度控制，2#Yankee電機為slave，控制方式為轉矩控制，兩臺電機為一個整體，要求速度同步。generation of control system will fully meet or exceed that of similar imported brand equipment, and meet the upgrading of equipment, with considerable flexibility and expansion.
In order to achieve the preset R & D objectives, at the beginning of the project, the brand and model selection of PLC, the core controller of the control system, has become one of the key factors affecting the success or failure of the project. After repeated comparison of various series PLCs of the mainstream brand PLC in the system, it is finally determined to select the latest small PLC s7-1200 launched by Siemens as the core controller of the control system of the new generation reflow equipment.
Jintuo's new generation RN (a) d reflow soldering equipment was launched on the market in the spring of 2010 and was immediately supported by our customers. Many superior performances such as the significant improvement of production efficiency, the significant reduction of energy consumption and humanized design have been highly praised by customers. The good performance of the equipment must rely on the high reliability and good
