12.20AO1 Terminal Analog Signal Mode

Factory Setting: 0

Settings 0 AVO1

1ACO1 (analog current 0.0 to 20.0mA)

2ACO1 (analog current 4.0 to 20.0mA)

Besides parameter setting, the voltage/current mode should be used with the switch.

AVI3 AVI4 AVO1 AVO2

ACI2 ACI3 ACO1 ACO2

12.21AO1 Analog Output Signal

		Factory Setting: 0
Settings	0	Analog Frequency
	1	Analog Current (0 to 250% rated current)

This parameter is used to choose analog frequency (0-+10Vdc) or analog current (4-20mA) to correspond to the AC motor drive’s output frequency or current.

12.22	AO1 Analog Output Gain		Unit: 1
	Settings	1 to 200%	Factory Setting: 100

This parameter is used to set the analog output voltage range.

When Pr.12.21 is set to 0, analog output voltage corresponds to the AC motor drive’s output frequency. When Pr.12.22 is set to 100, the max. output frequency (Pr.01.00) setting corresponds to the AFM output (+10VDC or 20mA)

When Pr.12.21 is set to 1, analog output voltage corresponds to the AC motor drive’s output current. When Pr.12.22 is set to 100, the 2.5 X rated current corresponds to the AFM output (+10VDC or 20mA)
