6.2 Fail-safe digital input
This manual describes the STO safety function with control via a fail-safe input. Additional
safety functions, additional fail-safe digital inputs of the inverter and the control of the safety
functions via PROFIsafe are described in the Safety Integrated Function Manual.
Defining a fail-safe digital input
If you use the STO safety function, then you must configure the terminal strip during the
basic commissioning for a fail-safe digital input, e.g. with p0015 = 2 (see Section Selecting
the interface assignments (Page 41)).
The inverter combines digital inputs DI 4 and DI 5 to form a fail-safe digital input.
