NOTICE
Destruction of the analog input as a result of the excessively high input current
The 10 V or 24 V voltage source will destroy the analog input if the operating mode selector
switch is set to "Current input" (I).
● Set the operating mode selector switch of the analog input to voltage (U).
Defining the safety-related input
You require a safety-related input to activate a safety function via the inverter terminal strip.
You can find additional information on safety-related inputs in the description of the STO safety
function.
Note
Control Units CU240B-2 and CU240B-2 DP do not have a safety-relevant digital input.

To use an analog input as additional digital input,
you must interconnect the corresponding status pa‐
rameter r0722.11 or r0722.12 with a binector input
of your choice.
You may operate the analog input as digital input
with 10 V or with 24 V.
The inverter combines two digital inputs to create a safety-re‐
lated input.
