This paper mainly points five parts: the first part introduces the elevator control system based on PLC of the development and application status。 The fifth part for the whole of elevator control system design, including a frequency converter to the parameters set, the writing of the ladder diagram, the adjustment of the elevator. In this paper, the control system through the reasonable selection of equipment, parameter setting and software design, use general converter and PLC for the five layers of elevator control.
