7.18 ANALOG INPUT CURVE CORRECTION (GROUP F4.1)
F4.1.09~F4.1.21 Analog input AI1~AI31 curve correction point/value 1~3
——
——
This group of parameters is used to conduct nonlinear correction to analog input value as required. Curve
correction of analog input AI1 is as shown in figure #-##, while the curve correction methods of AI2 and AI3
are similar to analog input AI1.
F4.1.17 AI3 hysteresis band dead
zone
Setting range: 0.00~2.00
Factory default: 0.10
Set hysteresis width of middle point between maximum value and minimum value of AI3, when it is applied
as bipolar signal, forward and reverse fluctuation of zero setting value will be frequent as shown in Figure
7-38. It should be set as 0 when applied as unipolar signal.
7.19 ANALOG OUTPUT (GROUP F4.2)
F4.2.22 AO1 function selection
Setting range: 0~45
Factory default: 0
F4.2.23 AO2 function selection/
standard expansion card
Setting range: 0~45
Factory default: 2
Multifunction analog output
AO1, AO2 can output voltage signal of 0~10V or current signal of 1~20mA,
selected by the dial switch on the control board. Frequency inverter status represented by the analog output
signal is set by this group of parameters. Please see Appendix 3 (comparison table of status variable).
F4.2.24 AO1 min value
Setting range: 0.00~10.00V
Factory default: 0.0
F4.2.25 AO1 maxi value
Setting range: 0.00~10.00V
Factory default: 10.00
F4.2.30 AO2 min value/standard
expansion card
Setting range: 0.00~10.00V
Factory default: 0.0
F4.2.31 AO2 max value/standard
expansion card
Setting range: 0.00~10.00V
Factory default: 10.00
This group of parameters defines the maximum and minimum of multifunction analog output AO1, AO2
allowed to output.
