Using current input A1I
In the Lenze setting, voltage signals in the range of ± 10 V are evaluated via the A1U input terminal.
If current signals are detected via the A1I input terminal instead, the selection "1: 0...20mA" or
"2: 4...20mA" is to be set in
.
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
takes place
in the event of a wire breakage (Lenze setting: "TroubleQuickStop").
