name can be activated for one brake.
The used brakes/actuators have to be electrically releasing, i.e. of the holding

Use both check boxes "Safe brake control (SBC)" to select if the connected
brakes is to be switched off safely.
If "Safe brake control (SBC)" has been activated (P–0–3265.0.1), the following
options can be selected:
Using the check box ""Allow release holding brake" with active "Safe torque
off (STO)"", manual brake control is enabled with the "Release holding brake"
control signal (P–0–3265.0.2).
When no brake or an electrically clamping brake has been parameterized ("self-
releasing"), i.e. the brake is applied at 24 V, a warning with regard to the brake
is displayed. Via the "Brake configuration" link, the dialog for Configuring the
brake can be opened in the standard firmware.

prevented by additional measures, e.g. a counterweight.
