该纸机传动系统采用由S7-226小型PLC作为系统的控制中心；由森兰SB70G系列变频器为驱动单元，频率分辨率为0.01Hz以上；变频专用电机作为执行单元；欧姆龙PLC提供速度反馈信号，使纸机传动在速度闭环运行，稳速精度达可达0.01%。由PLC通过西门子MODUBUS协议、RS485网络与变频器实现速度链功能、速差控制、负荷分配功能、总车速升、降、各分部点的速度升、降及紧纸、松纸等功能，较理想地满足纸机正常工作的需求。

3、速度链设计及速差控制

速度链结构采用二叉树数据结构算法，完成数据传递功能。首先对各传动点位置进行数学抽象，确定速度链中各传动点编号，此编号应与变频器内部地址一致。然后根据二叉树数据结构，然后根据二叉树数据结构，确定各结点的上下、左或右编号。即任一传动点由3个数据确定其在速度链中的位置，填入位置寄存器数值该传动点速度给变频器后，访问位置寄存器，确定子寄存器结点号，若不为0，则对该经点进行相应处理，直到该链完全处理完；再查兄弟寄存器结点号，处理另一支链。
