11-5 I/Os and Virtual Connections [500]
Main menu with all the settings of the standard inputs and outputs of the VSD.
11-5-1 Analogue Inputs [510]
Submenu with all settings for the analogue inputs.
AnIn1 Function [511]
Sets the function for Analogue input 1. Scale and range are defined by AnIn1
Advanced settings [513].
Communication information
Note When AnInX Func=Off, the connected signal will still be available for
Comparators [610].
Adding analogue inputs
If more then one analogue input is set to the same function, the values of the
inputs can be added together. In the following examples we assume that Pro-
cess Source [321] is set to Speed.
Example 1: Add signals with different weight (fine tuning).
Signal on AnIn1 = 10 mA
Signal on AnIn2 = 5 mA
[511] AnIn1 Function = Process Ref.
[512] AnIn1 Setup = 4-20 mA
[5134] AnIn1 Function Min = Min (0 rpm)
[5136] AnIn1 Function Max = Max (1500 rpm)
[5138] AnIn1 Operation = Add+
[514] AnIn2 Function = Process Ref.
[515] AnIn2 Setup = 4-20 mA
[5164] AnIn2 Function Min = Min (0 rpm)
[5166] AnIn2 Function Max = User defined
[5167] AnIn2 Value Max = 300 rpm
[5168] AnIn2 Operation = Add+
Calculation:
Default: Process Ref
Off 0 Input is not active
Max Speed 1 The input acts as an upper speed limit.
Max Torque 2 The input acts as an upper torque limit.
Process Val 3
The input value equals the actual process value (feedback)
and is compared to the reference signal (set point) by the
PID controller, or can be used to display and view the
actual process value.
Process Ref 4
Reference value is set for control in process units, see Pro-
cess Source [321] and Process Unit [322].
Min Speed 5 The input acts as a lower speed limit.
