Fast de-energization
Some brake rectifier types are equipped with two additional connections for switching the
brake load on the DC side. This allows the brake coil to be quickly deenergized, i.e. braking
starts earlier.
The Safe Brake Adapter supports such a fast de-energization using the two additional
connections -X15:1 and -X15:2. This function does not belong to the safe brake control.
