抽吸压辊（SUCTION PRESS）和成形辊（FORMING ROLL）通过网布，形成一个整体，要求速度同步。在抽吸压辊靠上烘缸之前，抽吸压辊为master，速度控制模式；当抽吸压辊靠上烘缸以后，

抽吸压辊转换为转矩控制模式，这时候，Yankee1为master，抽吸压辊和成形辊转变成Yankee1的从动辊，其控制模式转成转矩控制。

SP_R：速度给定T_R：转矩给定IQ_R：转矩分量给定  IQ_F：IQ电流反馈

TENS_R：转矩给定

图3为传动矢量控制图。从图中可以看出，逆变器的传动矢量控制由速度给定环节、速度调节器、D/Q轴电流调节器、磁通调节器、电压调节器、PWM控制器等组成。

在正常速度控制模式下，速度给定值(SP_REF1)通过FL总线从PLC传送到矢量控制系统给定积分单元，该单元将阶跃信号（SP_REF）转换为按一定变化率随时间而增减的输出信号(SP_R)，作为速度给定值，使调速系统的速度带有一定的加速度，并对加速度和减速度分别作出限幅再送到速度调节器。
