Chapter 4 Parameters|

Revision July 2008, EG03, SW V1.06

4-39

03 - 04

DC Fan Control

Factory Setting: 00

Settings

00: Fan runs on power up.
01: Fan begins upon a RUN command. Fan stops 1 minute after a STOP

command.

02: Fan begins upon a RUN command. Fan stops after a STOP command
03: Fan is controlled by temperature. Fan will be started at approximate

60°C.

This parameter determines DC fan control method.

03 - 05

Analog Output 1, (AFM1) 0~10Vdc

Factory Setting: 00

03 - 06

Analog Output 2, (AFM2) 0/4~ 20mA

Factory Setting: 01

Settings

00: Output frequency
01: Output current
02: Output voltage
03: Frequency command
04: Power factor loading

These

parameters

select

the content of the analog output signals AFM1 and AFM2.

Setting 00: 0-10V = 0 - (Pr.01-00)

Setting 01: 0-10V = 0 - (Double rated current)

Setting 02: 0-10V = 0 - (Pr.01-02)

Setting 03: 0-10V = 0 - Master Freq. command

Setting 04: 0-10V = 0.0 - output power factor 1.0

When using 0-20mA output, please refer to Pr. 3-14.

Maximum impedance loading of analog output 2 (AFM2) can’t be greater than 500 ohms.

03 - 07

Analog Output Gain 1

03 - 08

Analog Output Gain 2

Settings

01~200%

Factory Setting: 100

These parameters are to determine analog output gain.

The analog output is limited to 10V and 20mA. The gain is designed to offer a normally small

output signal to be enlarged for easier viewing on a meter.
