Note regarding Power/Motor Modules in the chassis format:
1)
For the chassis format, SBC is only supported by Power/Motor Modules with the number 3 or higher at the last position of
the Article number. For this design, a Safe Brake Adapter is also required.
Note regarding Power/Motor Modules in blocksize format:
2)
blocksize Power Modules additionally require a Safe Brake Relay for this function.
The Safe Brake Test is purely a diagnostic function, but for organizational reasons is included in the list of Safety Integrated
