摘　　要：针对针织热定形机的工艺特点和传统的调速机构同步控制存在的问题,研究一种用CAN总线,通过PLC和Lenze矢量型变频器组控制分布式多台电机的调速系统方案,实现PLC对以变频器为执行单元的传动系统的全数字现场总线控制,实现各传动点的速度链同步控制要求。描述主传动调速系统构成及主要控制功能,给出了系统的软硬件框图。经过设计、调试实现了系统控制目标。In consideration of the technology features of knitgoods heat setting machine and the synchronization control problem of conventional speed governing device, a speed regulating system based on CAN bus and Lenze frequency-conversion was developed. The all digital field bus control by the PLC to the drive system with the transducer was realized. The synchronous control demands of the speed chain were satisfied. This solution highlights the structure and chief functions of the leading drive speed regulating system. The block diagram of hardware and software for the system was presented. The control objectives of the system have been achieved by design and debugging.
