摘要
造纸生产流程中，各分部之间需要速度协调控制；在某些分部，如压榨部压榨形式采用真空辊带K式压榨时，为使K式压榨各传动电机根据各自的功率配置合理承担负荷功率输出，需采用负荷分配控制形式。整个生产线的速度协调问题可以选用PLC作为上位机，利用通讯实现对变频器的控制。森兰SB80变频器提供了丰富的串口协议，可方便组网控制。
In the process of making paper, all of the division need to coordination control in speed aspect. In some division, such as squeeze division, a K style squeezing of vacuum roller often used, for making every driving motor assume reasonable load powder output according to their power. It is necessity to the load distribution style. The problem of speed coordination control of whole as- sembly line can be solved by using PLC as supervisory computer. With communication control of frequency converter, Sb80 frequency converter provide abundant serial port protocol, and easy to network control.
