Fail-safe digital input

To enable a safety function via the terminal strip of the converter, you need a fail-safe digital
input. The digital inputs DI 2 and DI 3 can be used for the safety functions.
In the factory setting of the converter, the fail-safe digital input is not assigned to the
integrated safety functions. Only when commissioning do you define as to whether, for
example, you use digital inputs for the standard functions, or you create a fail-safe digital
input by combining them.
Wiring examples
An example for wiring the fail-safe digital input corresponding to PL d according to EN 13849-1
and SIL 2 according to IEC 61508 is given below:
