VVVF Inverter Drive and Data Network System Refine the Overall Performance and Functions

At Mitsubishi Electric, we produce the most technologically innovative elevator in the world. They benefit from our constantly evolving technology and our years of accumulative experience. Our elevators continue to establish benchmarks for quality in the industry, and consistently set new stadards for performance and reliability. The Series GPX (model) elevators exhibit this philosophy in every detail of design and concept.

VVVF Inverter Drive - Share a Ride in Comfort

Unique to Mitsubishi

Mitsubishi Electric was the first in the world to develop succesfully VVVF inverter control technology for high speed elevators. We also introduced inverters throughout the entire line-up-from low to super high-speed ranges.
Recent Advances have led to even further improvements in operation.

Precise, Effective Speed Control

Mitsubishi VVVF inverters make the ride much smoother by precisely adjusting speed control with voltage and frequency regulations. The inverters also include the latest low-noise modules to make the ride even quieter.

Even More Advances

Series GPX elevators use further advances to control the motor speed. Utilizing the lastest in semiconductor technology, Mitsubishi has incorporated on a single System LSI device, several control systems and our all new high speed digital signal processor.

Data Network System - Enhances the Human-Elevator Interface

A Proficient Network

The Data Network System uses microprocessor is specially designed for thought-processing, thus greatly enhancing the "Human Elevator Interface."

Highly Reliable and Efficient System

Each microprocessor is connected via a serial transmission line to ensure higher reliability and efficiency.
The system also shares diagnostic programs among the microprocessors and incorporates backup systems to further enhance reliability and passenger safety.

Intellegent Door System - Provides Stable and Sensitive Operation

An advanced RISC (Reduced Instruction Set Computer) microprocessor and VVVF inverters also control the elevator doors. This intelligent system detects the actual door load conditions at each floor and automatically adjusts the door speed and torque to suit. The result is stable, sensitive door opening and closing.
