安川变频器的应用第4讲安川变频器在造纸涂布机张力控制中的应用

摘要

张力控制主要由张力传感器、交流变频器和电动机组成。当张力太小时，经控制器处理后，变频器的频率就会增大，电动机的转速也随之提高。因而纸张就被拉紧，张力上升；反之亦然。本文主要阐述了安川变频器在造纸涂布机张力控制中的应用。%Tension controller mainly includes the tension sensor, AC drive and motor. When the tension is too small, the controller will increase the frequency of the inverter after the treatment, and the motor speed will rise too. This procedure will make the paper tight, and vice versa. This article focuses the Application of Yaskawa inverter in the tension control of the paper coating machine.
