7.4.4.1 Analogue input to any parameter
This function allows control of any parameter by using an analogue input. The parameter selects
what the range of control area and the ID number for the parameter that is controlled.
P2.4.5.6 Analogue input 3, minimum value ID1037
P2.4.5.7 Analogue input 3, maximum value ID1038
P2.4.6.6 Analogue input 4, minimum value ID1039
P2.4.6.7 Analogue input 4, maximum value ID1040
These parameters define the range for the controlled parameters. All the values are
considered to be integers i.e. when controlling the Field Weakening Point (as in example)
you also need to set numbers for decimals. e.g. FWP 100,00 needs to be set as 10000.
P2.4.5.8 AI3 Controlled ID ID1509
P2.4.6.8 AI4 Controlled ID ID1510
These parameters define the controlled parameter.
Example:
You want to control motor field weakening point voltage through 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

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