Abstract: An elevator system and/or method executed by an elevator controller for detecting a fault within the elevator system. The elevator controller utilizes the fault to disable a drive control portion of the elevator controller and activate a drive u-stop control portion of the elevator controller. The drive u-stop control portion of the elevator controller generates a signal based on at least one of a speed estimation, a velocity profile, and feedforward information. The elevator controller applies the signal to an inverter connected to the elevator controller to execute the urgent stop of an elevator car of the elevator system.

Abstract: An emergency power supply for a traction elevator system utilizes a microprocessor-based control arrangement with pulse-width modulator technology to create an efficient, cost-effective back-up power system for a traction elevator. The microprocessor-based control arrangement is used to sense a phase irregularity in the power supply. Upon sensing the phase irregularity, the microprocessor-based control arrangement disconnects the elevator system from the main power source and then generates a control signal to initiate the supply of back-up power. Once the elevator electrical system has been stabilized, the elevator control system will sense that recovery has occurred and will then provide an appropriate speed and direction command to the traction motor drive system.
