The target input for the analogue frequency reference
signal can also be chosen from the available
analogue inputs.

Given the standard I/O terminals on the RSI, there
are 2 analogue inputs available. In the programming
view, these inputs are referred to as follows:
Input type
(Graphical keypad)
Slot Input # Explanation
AnIN A. 1
Analogue input #1 (terminals 2/3) on board in Slot
A (standard I/O terminals).
AnIN A. 2
Analogue input #2 (terminals 4/5) on board in Slot
A (standard I/O terminals).
In the example above, the parameter AI1 signal
selection located in menu M3.5.2.1 with parameter
code P3.5.2.1.1, is by default given the value AnIN
SlotA.1 (graphical keypad). This means that the
target input for the analogue frequency reference
signal AI1 is now the analogue input in terminals 2/3.
Whether the signal is voltage or current, must be
determined with the dip switches. See the Installation
manual for more information.
This is what is shown in the parameter list on Group
3.5.2: Analog inputs:
Code Parameter Min Max Unit Default ID Description
P3.5.2.1.1 AI1 signal selection AnIN SlotA.1 377
Connect the AI1 signal to the
analogue input of your choice with
this parameter.
Programmable. See Group 3.5.2:
Analog inputs.
Assume you need to change the selected input.
Instead of AI1 you wish to use the analogue input on
your option board in slot D. Do as instructed here:
