6.1.2 Parameter setting
Short overview of the parameters for the analog input:
6.1.3 Using the analog input as current input
The current source must be connected to the X4/GND and X4/A1U plug connector.
Code C034
, selection "1" and "2", serves to reconfigure the analog input 1 to a current
input if a load resistor of 250 Ω is connected externally in parallel.
Tip!
The selection "2" serves to implement a 4 ...20 mA current loop, e.g. for fault-
resistant speed setpoint selection.
Open-circuit monitoring
Use C598/1
to set an open circuit error response for the 4 ...20 mA current loop. This error
response is already activated in the Lenze setting!
Minimum and maximum output speed
The speed range required for the application is set via the selection of the output speeds:
The maximum output speed which can be parameterised in code C011
is reached with
a speed setpoint selection of 100 %.
This value depends on the setpoint source and is considered as the reference speed for
all other settings.
The value which can be parameterised in code C010
corresponds to the minimum
speed if
– the input of the LS_AnalogInput block is connected to the X4/A1U input terminal
(Lenze setting)
and
– a voltage of 0 V applies to the X4/A1U input terminal.
