6.2.1 Parameterising analog input
By clicking on the button on the Terminal assignment tab, you reach the parameterising
dialog for the analog input:
Short overview of the parameters for the analog input:
Using current input A1I
In the Lenze setting, voltage signals in the 0 ... +10 V range are evaluated via the analog input A1U.
If current signals are to be detected via the input A1I instead, the selection "1: 0...20 mA" or "2:
4...20mA" must be set in C00034 .

Tip!
By selecting "2: 4...20mA", you can implement a 4 ...20 mA current loop, e.g. for stipulation
of the speed setpoint.
Open-circuit monitoring
In the case of configuration as a 4 ... 20 mA current loop, the fault response set in
C00598 takes place
in the event of a wire breakage (Lenze setting: "TroubleQuickStop").
