Engineering practice shows that INVT EC160 intelligent integrated machine has good control performance and stability on lift application.
Keywords: EC160, elevator solution, intelligent integrated machine.

I. Introduction
With the fast development of the construction, as a vertical transport tool, elevator is becoming more and more important. The current system in India market which use simple control board and general purpose inverter as a driver, can’t satisfy the user and not suitable for the high buildings.
EC160 elevator intelligent integrated machine is a new elevator intelligent control system developed under the design concept that integrates drive, control and network communication together. It adopts advanced closed loop vector control technology, elevator intelligent control technology and network communication technology, intelligent elevator drive, control and management together. It’s the complete and advanced solution for Indian lift market.

Basic performance
• Resources reducing in the elevator installation, debugging, operation and management.
• Max speed: 6m/s   Max floor: 64
• Intelligent network group control can control 8 elevators at the same time
• Embedded high-performance starting compensation technology of non-weighting sensor
• Advanced space vector calculation and be compatible to the encoder of AM/SM motor
• High-performance current vector control, 180% torque output at zero speed
• Low voltage emergency-rescue mode of AC220V single phase UPS, search the direction in light load
• Safety enabling hard ware input conform to EN81 standards
Special functions
• The initiate open PLC programming controller: provide the shifting/changing function for some terminals and further development platform for the user
• Hand terminal: stand-alone human-machine interface, on-line Chinese/English help system; functions of debugging management, debugging trace management, parameters uploading/downloading, computer data copying
• The hand terminal can be connected to the CAN interface in the car for convenient parameters setting
• Add TCP/IP internet module for remote debugging and control
• Support remote control of TCP/IP protocol

II. Configuration of residence lift
Normally, in India, residence lift has floors less than 8 floors. The mechanical is similar as the commercial lift. To the electrical system, rated power is lower because of low capacity such as 6 persons, in which case, 4KW system is most popular. Electrical configuration diagram of residence lift can be described as follow.
