Figure 7-8 Connection example for Braking Module Booksize Compact and braking resistor with a thermostatic switch
Note
The digital inputs (DI) are isolated and are referenced to M_DI (X21.5 and X21.6).
The reference point of the digital outputs (DO) is the ground GND of the 24 V supply.
Information on how to parameterize the digital inputs or digital outputs, see the SINAMICS S120/
S150 List Manual.
