4.3 Safety technology
The SR6 option adds the STO safety function to the SC6 drive controller via terminal X12.
For double-axis controllers, the STO safety function has a two-channel structure that acts upon both axes.
Information
If you would like to use the STO safety function via terminals, be sure to read the SR6 manual; see the chapter Detailed
information [ } 94] .

Information
In the case of a nominal brake current > 2.1 A, the system controller must ensure compliance with the maximum switching
frequency of 0.25 Hz.
