  • Elevator with master controller
    Patent number: 9988240
    Abstract: A system and method for controlling the movement of an elevator is provided. The elevator controller directs the operation of the elevator and receives information from the elevator system to calculate a brake profile. The elevator system transmits the brake profile to a master controller. The master controller selectively actuates the brakes to apply a braking force configured to generate the brake profile. The system and method may include local controllers, each configured to actuate a respective brake, wherein the master controller selectively directs the local controllers to generate a brake force commensurate with the braking profile.
