Using current input A1I/A2I
In the Lenze setting, voltage signals in the range of ± 10 V are evaluated via the A1U and A2U input
terminals. If current signals are detected via the A1I or A2I input terminals instead, the selection
"1: 0...20mA" or "2: 4...20mA" is to 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").
