.7.3.2.1 Analogue input to any parameter
This function allows control of any parameter by using analogue input. with parameters it is selected
what will be range of control area and ID number for paramter that is controller
2.3.2.6 Analogue input 1, minimum value
2.3.2.7 Analogue input 1, maximum value
2.3.3.6 Analogue input 2, minimum value
2.3.3.7 Analogue input 2, maximum value
These parameters are defining range for controlled parameter. All the values are
considered to be integers thus when controlling FWP as in example you need to set also
numbers for decimals. e.g. FWP 100,00 needs to be set as 10000.
2.3.2.8 AI1 Controlled ID ID1507
2.3.3.8 AI2 Controlled ID ID1511
These parameters define what controller parameter is.
Example:
You want to control motor field weakening point voltage by 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 filed weakening point
AI3/AI4 Output = Field weakening point voltage

Now analogue input 3 signal 0 V to 10 V (0 mA to 20 mA) will control field weakening
point voltage between 70,00 % - 130,00 %. When setting value, decimals are handled as
integer.
