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
2.4.3.7 Analogue input 1, maximum value
2.4.4.6 Analogue input 2, minimum value
2.4.4.7 Analogue input 2, maximum value
2.4.5.6 Analogue input 3, minimum value
2.4.5.7 Analogue input 3, maximum value
2.4.6.6 Analogue input 4, minimum value
2.4.6.7 Analogue input 4, maximum value
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
2.4.3.8 AI1 Controlled ID
2.4.4.8 AI2 Controlled ID
2.4.5.8 AI3 Controlled ID
2.4.6.8 AI4 Controlled 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.
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.
