The programme logic controller is utilized to control the inverter ' s output frequency which accomplishes controlling the velocity of speed - controlling asynchronous moter . the velocity between main asynchronous moter and speed - controlling asynchronous moter is composed by way of the differential planetary gear train , the tranmission system is made to regulate velocity stepless in large scope which succeed in controlling starting progress of load
使用可编程控制器对变频器的输出频率进行控制，实现对调速电机转速的控制。调速电机与主电机的转速经差动行星轮系的速度合成，可使传动系统在很大范围内无级调速，实现对负载的可控起动。
