Abstract

PURPOSE: To provide a control system for DC elevator, in which current blocking function of a thyristor converter is recovered at the time of stoppage of electric current, and at the same time brake resistance is connected to motor, whereby short-circuit current can be readily blocked and it is prevented that cage is operated at an overspeed when the short-circuit current is blocked.
