Delta Electronics VFD-G manual 03 - 04 DC Fan Control

Chapter 4 Parameters

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.
