Description of Safety Integrated functions
4.1 Safety Integrated basic functions
There are two options for registering this power unit with the system:
● Automatic brake identification when commissioning the system for the first time
– Requirements:
– During the first commissioning, SINAMICS checks at which power unit an SBA is
– For devices in the chassis format, if the SBA feedback signal (SBA_DIAG) is read in
● Manually defining the power unit
– Enter the component number of the power unit, to which the SBA is connected, into
– In parameter p9621 (p9621 = BICO interconnection to r9872.3), enter the digital input

Dis connecting the brake c able for s ervice purposes
As long as the brake is permanently released and not actuated, it is possible to briefly
disconnect the brake cable, e.g. for service purposes, and not receive fault messages. In the
case of a fault, message F07935 is only output when the brake is controlled.
