Dynamic Braking - Supplied in Models RB3, RB3B and RB3R. Provides initial braking torque andstops per minute as shown in Table5. The dynamic braking resistor is rated for stopping a typicalload when the motor load inertia does not exceed the motor armature inertia.HIGHER INERTIA LOADS AND/OR ARMATURE VOLTAGE HIGHER THAN RATED MAYEXTEND BRAKING TIME BEYOND THE WATTAGE RATING OF THE DYNAMIC BRAKINGRESISTOR.Table 5.
