8.1.9 DynamicBrakingUnit
In cases where a short stopping time is desired or a high inertia or regenerative load requires dynamic braking
capability, an optional Dynamic Braking (DB) unit can be added to the SG drive. Contact Benshaw for more
information regarding this option. Dynamic Brake Resistors are NOT included with the DB Unit.
