摘　　要：本文介绍了用ＰＬＣ控制龙门刨床交流变频无级调速系统的构成和性能特点，由于采用了转差频率闭环控制，较好地满足了工作台动、静态特性要求。制动采用能量回馈方式，保证了刨台往返的快速性。The system is adopted slip frequency close loop control that is satisfied the worktable requirement on both static and dynamic features. The design can save many materials, reduce maintenance work and time, increase the machine working efficiency and greatly reduce energy consum. The retrofit costs will be recouped in two years only by the savings.
