Configuring the digital inputs and digital inputs/outputs (X122/X132)



The digital inputs and digital inputs/outputs (X122/X132) are mainly assigned to SINAMICS Integrated. Through configuration (frames 39x), you can, however, also use the digital inputs and digital inputs/outputs (X122/X132) for the CPU. The following applies:

A digital output is always only available exclusively to SINAMICS Integrated or to the CPU.

If you use a digital input for the CPU, you can also interconnect the digital input at the drive end.

You can configure the digital inputs and digital inputs/outputs (X122/X132) channel by channel. To do so, go to the function view in the project tree under "Automatic speed control" > "Parameter assignment" and set the configuration under "Inputs/outputs".

Bidirectional inputs/outputs are configured in the following configuration mask.


圖片: Bidirectional inputs/outputs

You can assign the SINAMICS digital inputs and digital inputs/outputs (X122/X132) using frame 39x of the PU. The status information of the digital inputs and digital outputs is then transferred at the PROFIdrive PZD sampling rate (p2048). The inputs/outputs are also sampled in the configured sampling time for the digital inputs and digital inputs/outputs (p0799). The application of the output values and return of the input values are therefore subject to dead times and jitter.

提示 Interface X142 If you have particularly strict requirements for the digital input/outputs, use the digital input/outputs at interface X142. The digital inputs/outputs can be operated in isochronous mode and allow very short response times.
