Setting of the Braking Module activation threshold
The value of the Braking Module activation threshold p1362[0] and the hysteresis p1362[1]
can be adjusted. Depending on the voltage type, the parameters are assigned different
values depending on the factory setting of p0210.

Activating the "Braking Module" function
You have opened the STARTER commissioning tool and created a new project or opened
an existing project.
Activating the Braking Module
1. Configure the Control Unit and the infeed module as usual (see SINAMICS S120
Commissioning Manual with STARTER).
2. Select "Vector" as drive object type.
