CHAPTER 4 - VARIOUS FUNCTION SETTING & DESCRIPTION

4.1 Function Setting

4.1.1Basic function parameter setting

It is the basic function setting. All settings are factory defaults unless users make change. It is recommended to use factory setting value unless the parameter change is necessary.

1) Common parameter setting

The following table shows common parameter setting that should be checked before use but making change does not affect inverter control type.

Parameter Name

Description

 

 

 

Rated Motor

FU2-30

Select motor and voltage rating suitable to the desired

Selection

inverter

 

 

 

Basic parameter value setting when selecting the motor

Parameters related to

 

rating.

FU2-31 ~ 36

Note) If there is any discrepancy between parameter

motor

preset value and the actual motor parameter value,

 

 

 

change the parameter value according to the actual

 

 

motor.

Drive Mode

DRV-3

Operation via Keypad, Fx/Rx-1, Fx/Rx-2 setting enable

Frequency

DRV-4

Frequency/Torque setting parameter

or

It automatically changes to torque mode when FU2 39-

Torque Mode

 

[Control mode] is set to Sensorless_T, Vector_TRQ

Accel/Decel time

DRV-1, DRV-2

Setting Accel/Decel time enable

setting

 

 

 

 

 

2) V/f control

FU2-39 [Control mode] is set to 0 (V/F) as factory setting. Operation via V/F control can be performed after common parameter settings are done and the followings are set.

Parameter Name

Code

Description

 

 

 

Starting freq.

FU1-22

Setting frequency to start the motor

 

 

 

Torque boost

FU1-26

Manual or Auto torque boost settable in this parameter

 

 

 

 

Torque boost value in

FU1-27, FU1-28

If FU1-26 [torque boost] is set to manual, user sets the

FWD/REV

desired value and the direction in code FU1-27 and 28.
