摘要： At the beginning of a run of an elevator 4, from an elevator control 14 a stiction removing velocity signal 20 is provided to a drive control 24 for commanding the elevator until stiction is broken; then as soon as the elevator 4 moves a normal dictated velocity signal 21 controls the elevator 4 throughout the remainder of the run. In further accordance with the present invention, the stiction removing velocity signal 20 is provided prior to the dictated velocity signal 21 only when the elevator 4 is operating in a regenerative mode, as determined by the elevator 4 moving in the up direction while lightly loaded or moving in the down direction while heavily loaded.
