A drive control system is one of the fundamental elements to constitute an elevator in that its motive power will govern the basic function of elevator’s ability to transport passengers vertically and comfortably. In this regard, much attention has been paid to the performance of the drive control system by both customers and manufacturers. This drive technology developed rapidly with the introduction of inverter control. In this paper, we will describe the latest drive technology for traction and hydraulic elevators focusing on inverter control.
