Instructions for using the three motor parameters of the soft starter

Publish Time: Author: Site Editor Visit: 20

Design purpose

Solve the trouble of frequent modification of motor parameters by one soft starter to take three motors with different power respectively;

Use Instructions

The following parameters must be modified: 

Function Code

Name

Parameter Description

Setting Value

A05

Number of sequential starts

Selection of the number of control motors

3

C03

Multi-function input In1(DI1)

Terminal function selection

3

C04

Multi-function input In2(DI2)

Terminal function selection

3

A06

-

A11

The First motor parameters

The first motor parameters

 

A12

-

A17

The second motor parameters

The second motor parameters

 

A18

-

A23

The third motor parameters

The third motor parameters

 

For Example

 

One 11kW/380V Soft Starter to run with 5.5kW, 7.5kW, and 11kW motors respectively, the motor parameters are entered into the A06-11, A12-17, and A18-23 parameters.

 

1、 When In1(DI1),In2(DI2) and COM do not conduct, the soft starter will use the first motor parameters;

2、The soft starter will use the second motor parameter when In1 (DI1) is conducting with Com In2 (DI2) is not conducting with Com;

3、When In1 (DI1) is not conducting with Com In2 (DI2) is conducting with Com, the soft starter will use the third motor parameter.

Test Method:

It is possible to use one motor to test different effects with motors by changing the parameters of the second and third motors, together with the on/off of In1 (DI1) and In2 (DI2).
