Keywords: EC160, elevator solution, intelligent integrated machine.
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 drive, 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.

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.

• Intelligent integrated: EC160 is the combination of controller and inverter.
• 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.
Higher performance and easy debugging save both time and material cost. With the advanced technology and high cost-effective, EC160 is more and more popular in the global market.
