● Digital inputs (DI)
● Bidirectional digital inputs/outputs (DI/DO)
Bidirectional digital I/Os can be configured individually as digital inputs or outputs.
Assignment of the I/Os to functions can be parameterized as required. Special functions (e.g.
input of the measuring input) can be assigned to the I/Os.
The digital inputs/outputs on the X122 front connector can be used by either SIMOTION or
SINAMICS (e.g. as enable signal for a drive).

● Freely addressable I/Os
● I/Os that are assigned to
● Measuring inputs
● Inputs for the external
● Cam outputs

Note
For optimal noise immunity of the digital inputs, the use of shielded cables is necessary in
certain cases. This is necessary when the digital inputs are to be used as
● Inputs of measuring inputs or
● Inputs for the external zero mark
