发明名称 METHODS AND SYSTEM FOR STOPPING ELEVATORS
摘要 The invention relates to methods for stopping elevators especially when using at least one three-phase motor (14) operated by a static frequency converter (18). According to the invention, a brake relay (6) controls the brake (15) of the motor (14) such that releasing of the brake relay (6) causes the motor (14) to be decelerated while the brake relay (6) is coupled to a protective circuit (9) in such a way that the control pulses required for generating the driving motor field are safely blocked when the brake relay (6) is released.
