Method and apparatus for operating an elevator drive in different performance modes

摘要

An elevator system for controlling movement of an elevator car coupled to a drive to serve floors in a building in response to hall calls generated from a plurality of hall call devices located at floors served by the elevator car, includes a control for generating a velocity pattern signal from stored parameter values representing desired jerk, acceleration and constant speed relative to time. The drive responds to the velocity pattern signal to move the elevator car to the floor associated with each hall call. The control selectively generates a high performance velocity pattern signal and an energy conservation velocity pattern signal in response to parameter values that can be changed by user input. Sensing a predetermined condition such as the application emergency power to the drive and/or a high wind speed automatically modifies the velocity pattern signal.
