Calibration routine with adaptive load compensation |
摘要 |
A load compensation calibration method for an elevator controller includes the steps of moving an elevator car in a first direction, the first direction a first creep speed region; determining the time to travel a given distance; during the first run; determining a first actual creep speed of the first creep speed region; determining a difference between a dictated creep speed and the first actual creep speed; determining a first compensation frequency for minimizing the difference between the dictated creep speed and the first actual creep second; moving the elevator car in a second direction, the speed direction including a second creep speed region; determining the time to travel a given distance during the second run; determining a second actual creep speed of the second creep speed region; determining a difference between a dictated creep speed and the second actual creep speed; determining a second compensation frequency for minimizing the difference between the dictated creep speed and the second actual creep speed; and creating a load compensation characteristic in response to the time to travel a given distance and the first and second compensation frequencies.
