Safety-related input
This manual describes the STO safety function with control via a safety-related input. All
other safety functions, additional safety-related inputs of the inverter and the control of the
safety functions via PROFIsafe are described in the Safety Integrated function manual.
Defining the safety-related input
If you use the STO safety function, then you must configure the terminal strip during the
quick commissioning for a safety-related input, e.g. with p0015 = 2.
Terminal strips on CU240E-2 Control Units (Page 100)
The inverter combines digital inputs DI
4 and DI 5 to create a
safety
-related input.
