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.
