S120变频器在排锯伺服控制改造中的应用

Application of S120 Frequency Converter in Reform of Servo Control for Gang Saw

管排锯主轴和挡板小车运行和定位由4台西门子伺服电机驱动,控制系统为611U变频器。西门子611U变频器已停产,备件采购困难且造价高昂。现场广泛使用的S120变频器,备件通用,维护方便。用S120系统作为611U系统备用系统,进行数据同步,灵活切换,可以避免因为主传动系统故障导致大量的停机时间影响产线生产。采用新的S120系统做备用系统后,保证了生产线的安全运行,提高了产能和设备保养维护效率,同时对设备进行了升级改造,延长了使用寿命和周期。

The spindle of gang saw,running and positioning of baffle trolley are driven by four Siemens servo motors as well as the control system is 611U frequency converter.The Siemens 611U frequency converter has gone out of production,so the spare parts purchase is difficult and manufacturing cost is high.The spare parts of S120 frequency converter that is widely used in field are universal and it is with easy maintenance.A lot of downtime caused by main drive system failure could be avoided by using the S120 system as backup system of 611U system to synchronize data and switch flexibly so as to avoid affecting productions.After adopt the new S120 system as backup system,the safe operations of production line is ensured,production capacity and maintenance efficiency of equipment are improved as well as the equipment is upgraded and reformed so that the service life and cycle are extended.
