6.2.1 Parameterising analog input
By clicking on the Terminal assignment tab, you reach the parameterising dialog for the analog
input:
Short overview of parameters for the analog input:
Using the analog input as current input
In the Lenze setting, a voltage signal in the range 0 ... +10 V is evaluated via the analog input termi-
nal A1U.
For evaluating a current signal:
1. Connect external 250-Ω load resistor.
2. Make the following setting in
C034/1 :
• Selection "1: 0 ... +5 V" for 0 ... 20 mA current loop.
• Selection "2: +1 ... +5 V" for 4 ... 20 mA current loop
("life zero", with open-circuit monitoring).
3. With a configuration as 4 ... 20 mA current loop in C598/1 , set the desired error response in the
event of open circuit (Lenze setting: "Fault").
