● STO is selected in operation.
● At the same time, the drive activates SBC.
● Taking the brake closing time into account, the command to close the motor holding brake
closes the brake, thus supporting the shutdown process initiated by STO.
● The mechanical brake brakes the motor to a standstill.
● STO is deactivated by the drive with (manual or automatic program-controlled) deselection.
● The drive is again "ready for switching on".
● SBC is also simultaneously deactivated with deselection of STO. The brake remains (unsafely)
closed, however, until the standard program executes the command to open the brake
● You restart the drive with a positive signal edge at ON/OFF1.
Taking the brake opening time into account, the command to open the brake opens the brake.
● STO is selected via the control bit of the selected PROFIsafe telegram or via the F-DI.
● The drive activates SBC when the safe brake control is enabled (p9602 = 1).
● The drive triggers SBC simultaneously with STO.
● Brake management is resulted within the context of standard parameterization of the drive.
