Elevators transport passengers and goods within buildings. Besides lifting, the primary functions of an elevator are safety and a comfortable ride.
Every Delta elevator drive is equipped with a 32-bit high speed CPU. This CPU provides fast response, high output torque, precise positioning control and other outstanding features which ensure that the elevator is perfectly level with the landing floor whenever the door opens. The CPU rapidly recalculates the starting torque requirement for different weights in the elevator. This ensures a smooth ride. It also determines the car load precisely to prevent null-speed slipping of the elevator.
For additional energy savings, the AFE2000 Series Active Front End Unit from Delta is a power regeneration device. The AFE2000 can improve the quality of the system power. It collects the regenerative energy of the elevator and converts it into reusable electricity for other consumers. Delta has also introduced the IED Series Integrated Elevator Drive for other industrial needs. The Integrated Elevator Drive combines a host controller and drive function into a single drive unit. This simplifies procurement and maintenance processes and ensures ride reliability and safety. 40% energy savings can be achieved with an elevator solution using the AFE2000 Series with Delta's elevator drive and permanent magnet motor.
