摘要
离心浇铸机两驱动辊在运行过程中既要保持同步,又要保证两台电机的负荷平衡。利用西门子6SE70变频器的主从控制方式的双闭环控制系统就可解决该问题。介绍了基于变频技术的离心浇铸机控制系统的硬件系统构成和主要功能,给出了系统监控画面设计。实践证明,该方法简单易行,解决了控制系统中负荷分配不均的问题。
The two motor driving rollers of the centrifugal casting machine must keep synchronous and keep load balance. It could be solved by siemens 6SE70 inverter. The hardware system structure and main functions of monitoring system of centrifugal casting machines based on inverter technology were introduced. The practice showed that this method was simply practical and overcome the variance of load distribution.
