I.Introduction
Mitsubishi elevator is the top 10 reputed elevator brand in the world, and has big market share in India. Mitsubishi has its own special control system and motor. They are not compatible with other brand control system and motor. So Mitsubishi ruled the after sales service market. Any parts broken, the end users have to go with Mitsubishi costly spare parts. So the users complain a lot but no other choice.
Now INVT has developed EC160 elevator intelligent integrated machine which can drive Mitsubishi motor and replace the whole control system. It can break the monopoly of Mitsubishi on after sales service market. EC160 elevator intelligent integrated machine has the following features.

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
Support both serial and parallel communication.
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

2.Advantages
Intelligent integrated: EC160 is the combination of controller and inverter.
Support dual communication methods: Serial and parallel communication.
Simple and stable: 2 sets of CAN communication interface makes the system simple, high efficient and stable.
Easy debugging: LCD operator with 10 rows display can show all the running state information. It makes debugging easier.
ARD function: With single phase 220VAC UPS, EC160 can run to the nearest floor and open the door when grid power is off.

IV.Conclusion
After retrofitting by EC160, the Mitsubishi elevator runs perfectly. The customer is very satisfied. It proofs that the monopoly can be broken. More and more customers will choice INVT EC160 to replace Mitsubishi system in future. EC160 has broad market prospects.
