Introduction

KOYO elevator combines with the “magic merit”of the modern science and technology. The system applies industrial field bus technology into the elevator design, providing safe, accurate, and quick performance. Every action of the elevator is under strict control by microcomputer processor. Powerful self-diagnostic function and watchdog system guarantee high efficiency and reliability. Sound interface makes commissioning and modification more convenient, which fully meets the changing requirements of building and passengers.
 

Mature vector FM&PM inverter technology is adopted for controlling. It perfectly applies the optimum speed changing curve outputted by control system after precise calculation to the running of elevator, eliminating the discomfort during riding, and the speed change happens unwittingly during elevator's starting-up, running and stopping.
