Abstract

A method of adjusting an elevator creep speed includes the steps of determining an actual creep speed; determining a difference between a dictated creep speed and the actual creep speed; determining a compensation frequency for minimizing the difference between the dictated creep speed and the actual creep speed, the compensation frequency being determined in accordance with a load compensation characteristic; and adjusting the elevator creep speed in response to the compensation frequency.
