Panoramic elevator MITSUBISHI Electric Elevator Escalator
GPM-III, 16-24 Pers, 200m

High-speed computer processing is behind precise adjustment of elevator machine controls to eliminate noise and vibration during operation. To ensure safety during boarding, door sensors detect passengers and objects in the area near the doors.

An exclusive elevator control system that integrates digital control circuitry into a high-accumulation LSI results in added performance and reliability. High-speed processing enhances motor control precision to deliver a more comfortable ride. The low-noise PWM (pulse width modulation) inverter unit incorporates the latest power IC module, while the cooling unit uses the highly efficient heat-pipe method to deliver even greater reliability and space savings.

Mitsubishi Electric elevators use a VVVF Inverter Drive control system to ensure doors open and close smoothly and quietly. A high-efficiency, one-chip RISC microcomputer enhances the doors%u2019 sensitivity by calculating the weight of the door panels at each floor, the strength of the wind, and even waste in the sill groove. Auto Tuning provides just the right door opening and closing speed at each floor for safety and reliability. In addition, the learning-capable Door Load Detector offers high-precision door sensitivity, monitoring changes at each floor to allow prompt door-motion return when abnormal pressure is applied.

(optional)
Prevents passengers from being caught by the doors, using multiple infrared light beams mounted along the entire length of car door edge. Doors reverse and open if beams are blocked during door closing.
