      Information

      Information

      Overview Manuals Common Applications Product Precautions
      Allen-Bradley 1305-KBA09 is a dynamic brake assembly for 5 HP, 460 V AC Bulletin 1305 drives, restricted to Series B or later.
      • Dissipates regenerated energy during deceleration
      • Integrates with the Bulletin 1305 braking circuit
      • Supports intermittent controlled machine stopping
      • Uses an internal fuse and overtemperature thermostat

      The brake resistor connects to the drive DC bus when regenerated energy raises the bus voltage. Application selection depends on braking torque, deceleration time, load inertia and duty cycle.

      Important Notice: Do not use 1305-KBA09 with a Series A 1305 drive. Keep the braking cycle within the 20% maximum duty rating and provide auxiliary stopping where loss of braking could endanger personnel.

      Allen-Bradley 1305-KBA09 Manuals & Downloads
      Allen-Bradley 1305-KBA09 Technical Reference (PDF)Allen-Bradley 1305-KBA09 Dynamic Brake Installation Instructions (PDF)

      The technical reference covers brake selection, operating limits and fault decisions. The separate manufacturer manual provides the original mounting, DC-bus wiring and DB Enable instructions.

      Controlled deceleration
      Absorbs regenerated energy while a compatible 5 HP 1305 drive ramps its load down.
      Intermittent braking cycles
      Supports braking cycles selected against torque, peak power and the 20% maximum duty limit.
      Inertial-load evaluation
      Uses motor speed, reflected inertia and stopping time to assess brake demand before installation.
      Exact brake replacement
      Restores a 1305-KBA09 position after matching the drive series, DC-bus wiring and DB Enable setting.
      Read the Allen-Bradley dynamic brake installation instructions before work. Match 1305-KBA09 to a Series B or later 1305 drive and verify the machine stopping arrangement before commissioning.
      1
      Confirm the 5 HP, 460 V AC 1305 drive is Series B or later; reject a Series A pairing.
      2
      Place the machine in its approved maintenance state and retain an independent stopping method where required.
      3
      Remove all power and allow at least 60 seconds for the DC bus to discharge before work.
      4
      Mount the brake vertically outside other cabinets with unrestricted cooling airflow.
      5
      Connect BRK, GND and +DC to the corresponding drive terminals using the installation wiring diagram.
      6
      Keep terminal conductors within 0.75 to 4 mm2 and do not exceed 1.81 N m terminal torque.
      7
      Set P.011 DB Enable to Enable and check the planned braking cycle against torque and duty limits.
      8
      Investigate thermostat trips or repeated fuse failures before releasing the machine to operation.

      Technical notes

      Technical notes

      Match the drive series before connection. Set P.011 DB Enable to Enable. A thermostat trip disables the brake; repeated F1 fuse failures require brake replacement rather than repeated fuse substitution.

      FAQS

      • Can 1305-KBA09 be connected to a Series A 1305 drive?
        No. This brake is restricted to Series B or later. Connecting it to Series A can damage components or cause drive failure.
      • When does 1305-KBA09 begin dissipating motor energy?
        Regeneration raises the drive DC-bus voltage during deceleration. The brake circuit then connects its resistor across the bus and releases that connection as voltage falls.
      • Does the 20% duty rating make 1305-KBA09 suitable for continuous braking?
        It does not. The maximum duty cycle is 20%; the 100% torque rating is a typical 20-second braking interval, not a continuous operating rating.
      • What should be reviewed if a 1305-KBA09 application trips on overvoltage while slowing?
        Compare calculated peak braking power with the 3.4 kW assembly limit. Increasing deceleration time or reducing reflected inertia can lower the required peak power.
      • Which 1305 setting activates an installed 1305-KBA09?
        Set P.011, DB Enable, to Enable and retain the change in the drive configuration record.
      • How should repeated F1 fuse failures in 1305-KBA09 be handled?
        F1 is specified as Gould Shawmut A60Q10-2, 10 A at 460 V. Repeated failures require brake replacement; the brake assembly is not repairable.
      • What happens when the 1305-KBA09 thermostat trips?
        The brake is disabled to prevent overheating. The machine design needs an auxiliary stopping method if reduced braking torque could create a personnel hazard.
      • Why must 1305-KBA09 be mounted vertically with unrestricted airflow?
        Regenerated energy becomes resistor heat. Mount the brake outside other cabinets in a vertical position, with the clearances required by its installation drawing.
