7.10 Brake control and automatic brake
If your motor has a holding brake, this brake can be actuated as required by the
application. The servo drive can only control holding brakes with a rated voltage of 24 V
DC. If you want to edit the parameter for controlling the holding brake, open the menu
Parameters/Device parameters/Brake functions. The following window will be displayed:
Figure 109: "Brake functions" window
One of the digital outputs is reserved for controlling the holding brake of the motor. The
brake will be enabled when the servo drive is enabled. Delays can be configured for
holding brakes with high mechanical inertia.

The Run delay t
F
is used to adapt the actuation of the holding brake to its mechanical
inertia. If the servo drive is enabled, the speed setpoint will be set to zero during this delay.
As a result, the drive stands still until the brake has been completely released.
