This paper mainly presents INVT EC160A intelligent integrated machine used for retrofitting of KONE elevator in India. It gives the detailed retrofitting solution for KNOE elevator and commissioning details. Engineering practice shows that INVT EC160A intelligent integrated machine has good control performance and stability on KNOE elevator.

Keywords: EC160A, KNOE elevator retrofitting, intelligent integrated machine.

I. Introduction

KONE elevator is the top 5 elevator brand in the world, and has very big market share in India. KONE has its own special control system and motor. They are not compatible with other brand control system and motor. So KONE ruled the after sales service market. Any parts broken, the end users have to go with KONE costly spare parts. So the users complain a lot but no other choice.

Now INVT has developed EC160A elevator intelligent integrated machine which can drive KONE motor and replace the whole control system. It can break the monopoly of KONE on after sales service market. EC160A elevator drive 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. Encoder retrofitting

2.1 Install the encoder as showing in the below picture:

2.2 Use M3 screw to fix the sensor on the bracket, as showing in the below picture:

2.3 Use M4 screw to fix the bracket on the flange plate of the encoder. The sensor should be under the bracket near the motor wheel side as showing in the below picture, and use glue to fix the magnet:

2.4 Connect the sensor signal to EC160A SUDZ and power cable to 24+ and 24-:

2.5 Make the encoder cable connection according to the below list
