Setting the safe brake test in the inverter

The sequence of the brakes that are to be tested must match the configuration in the SINAMICS S120
and at the F_BRAKE_TEST. Otherwise, when carrying out the test, the block and the SINAMICS
S120 output an error.
The parameters of the test sequences are set in SINAMICS S120, the selection as to which test se-
quences are to be performed and how is specified at F_BRAKE_TEST.
