Examples of Safe Motion: Muting with Safe Direction (SDI)

Structure of the Safety Function

The block diagram shows the logical structure of the safety function,
consisting of the series alignment of the safety-related subcircuits (SRP/CS).

In conjunction with light curtains and a muting circuit, the safe direction function (SDI) has a positive effect on safety because the respective direction of the drive axis is monitored during the muting phase and a safe shutdown occurs in the event of an error.

Determination of the performance level for the overall circuit

The performance level corresponds to the result from the example of the safe stop function.
