Series GPX Standard Passenger Elevators

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

At Mitsubishi Electric, we produce the most technologically innovative elevators in the world. They benefit from our constantly evolving technology and our years of accumulated experience. Our elevators continue to establish benchmarks for quality in the industry, and consistently set new standards 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 successfully 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 latest 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 microprocessors distributed throughout the elevator configuration for more flexible control of the overall system. Each 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 furfher enhance reliability and passenger safety.

Intelligent 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.
