Preface

The -S3 Series of elevator-used Inverters is a new type inverter which is

researched and developed based on the carry characteristic of elevator. The 32

bit electromotor-used Digital Signal Processing (DSP), Complex Programmable

Logic Device (CPLD), Intelligent Power Module (IPM) and the digiral vector

controlled frequency-variable speed-adjustable technology are used in the

Inverter. It also combines the model characteristic of potential energy. All of them

ensure stable, comfortable and efficient running of elevator.

Outline

This instruction manual describes installation, operation, function constants

setting, maintenance and trouble-shooting of the -S3 Inverter. The

manual can be the reference for designing the elevator control system by using

the -S3 Inverter. It also can be the reference of installation,

commissioning and maintenance of elevator.

Please read the manual carefully before installing and operating the inverter.

Innovations

a) The innovative starting compensation technique without load sensors

provides an excellently comfortable starting of elevator.

b) The new PWM dead-zone compensation technique can effectively reduce

motor noise and wearing.

c) There is no need to run autotuning for asynchronous motor.

d) There is no need to lift the car during self-tuning of the phase angle of

elevator with synchronous motor.

-S3 Inverter for Elevator

Convenient and quick commissioning method of elevator

It is important whether it is convenient for elevator commissioning after wiring.

Usually it takes operators much time and effort to set many parameters and

perform complicated procedures. This becomes very convenient by using our

inverter which is designed especially for elevator. There are only three steps for

commissioning:

1 Adjusting running direction

The correct encoder wiring and motor running direction can be easily identified

by the operator.

2 Setting parameters

a) Users may use the leave-factory configuration of motor parameters directly

identified and/or set by us, or

b) Enter the motor parameters into the inverter according to the motor

nameplate.

3 Adjusting feeling

a) The comfortable feeling may be obtained by the leave-factory values of the

parameters.

b) This may be further improved through minor adjustments of C parameters

of PID.
