Fail-safe digital inputs

In the factory setting of the inverter, the fail-safe digital inputs are not assigned to the
integrated safety functions. It is only at the parameterization stage that you define, for
example, whether digital inputs DI4 and DI5 are to be used for standard functions or whether
a fail-safe dual-channel input is to be created by merging.

Safety-related signals, e.g. the switching state of a sensor, must be wired on two channels
with a fail-safe digital input. The inverter evaluates the signal on two separate signal paths.
