摘要
针对交交变频传动装置启动过程中出现过电流故障的问题,对其产生原因进行了分析,并提出在原传动系统速度控制软件包中增加启动过电流防护控制程序方案,试用后,效果很好。
In view of the problem of over-current of SIMOVERT D drives during mill star-up,the causes were analyzed,and the resolution scheme which add the prevention program in the original speed control software of drive system was used.At last,the good effects were obtained.
