PROBLEM TO BE SOLVED: To check vertical car vibration when elevators land at floors. SOLUTION: If balance control at an elevator start involves torque compensation, an arithmetic section 15 effects, when the elevator lands at a floor, not door-open-in-run control where the door is opened while the car is stopping but door-open-on-stop control where the door is opened after the car has stopped, which eliminates vertical car vibration that would otherwise occur when the elevator lands at floors. |
