The B3 brake type is a single-disk brake with 2 friction surfaces. The brake can be
ordered for the drive as an option. It is fully integrated into the drive and is powered
and controlled internally via the drive electronics with DC 24 V.
The brake operates according to the spring-force brake principle, while the braking
torque is built up when the power is switched off. It is designed as a holding brake with
emergency stop function. The low mass moment of inertia enables optimal dynamics.
