铸造起重机的主从控制变频调速系统

Master/follower control type variable frequency speed regulation system

结合实例 ,根据钢厂铸造起重机的特殊性 ,在PROFIBUS总线和主从控制用宏变频调速系统的基础上 ,研制出适合恶劣工作环境的主从控制变频调速系统 ,其性能好 ,工作级别高 ,成本低 ,市场竞争力强。

Cradle crane for steel plants operates in harsh conditions and is required to have high duty classification and safe coefficient.This paper discusses Profibus and master/follower macro-control based variable frequency speed regulation system that have been successfully used in a sluicegate hoist and develops a new master/follower control variable frequency speed regulation system that can operate in harsh condition and features high duty classification,low cost and good competitiveness.
