5.4.3.1
Analogue input to any parameter
This function allows you to control any parameter by using an analogue input. Use a parameter to
select the range of the control area and the ID number for the parameter that is controlled.
2.4.3.6
Analogue input 1, minimum value
ID303 “AI1 Scale Min”
2.4.3.7
Analogue input 1, maximum value
ID304 “AI1 Scale Max”
2.4.4.6
Analogue input 2, minimum value
ID393 “AI2 Scale Min”
2.4.4.7
Analogue input 2, maximum value
ID394 “AI2 Scale Max”
2.4.5.6
Analogue input 3, minimum value
ID1037 “AI3 Scale Min”
2.4.5.7
Analogue input 3, maximum value
ID1038 “AI3 Scale Max”
2.4.6.6
Analogue input 4, minimum value
ID1039 “AI4 Scale Min”
2.4.6.7
Analogue input 4, maximum value
ID1040 “AI4 Scale Max”
These parameters define the range for the controlled parameter. All the values are
considered to be integers, so when you are controlling FWP as in the example, you also
need to set numbers for the decimals. For example, FWP 100.00 must be set as
10000
.
2.4.3.8
AI1 Controlled ID
ID1507
“AI1 Control. ID”
2.4.4.8
AI2 Controlled ID
ID1511
“AI2 Control. ID”
2.4.5.8
AI3 Controlled ID
ID1509
“AI3 Control. ID”
2.4.6.8
AI4 Controlled ID
ID1510
“AI4 Control. ID”
These parameters define which parameter is controlled.
Example:
You want to control Motor Field Weakening Point Voltage by an analogue input from
70.00% to 130.00%.
Set Scale min to 7000 = 70.00%.
Set Scale max to 13000 = 130.00%.
Set Controlled ID to 603 Voltage at field weakening point.
AI3/AI4 Output = Field weakening point voltage

Figure 23.
The analogue input 3 signal 0 V to 10 V (0 mA to 20 mA) will control the field weakening
point voltage between 70.00% and 130.00%. When setting a value, decimals are handled
as integers.
