摘要
通过把变频器的外部频率给定端子与电控系统PLC的模拟量输出端子连接,实现了主风机风量随提升机主电机定子温度的变化而自动调节,大幅度地提高了风机效率。
By means of connecting the exterior setting point of converter sequence to the analog output of hoist control system, the airflow of motor cooling system can be regulated automatic by PLC. So the efficiency of motor cooling system is great increased.
