Dynamic Braking Solution — Allen-Bradley 1305-KBA09 | 1305 AC Drive Series
Where This Product Is Used
The Allen-Bradley 1305-KBA09 Dynamic Braking Kit is engineered for applications where rapid, controlled deceleration is critical. Engineers specify this accessory across a wide range of industrial environments:
- Material Handling & Conveyors — Prevents coasting and load runaway on inclined or high-inertia conveyor systems.
- Packaging Machinery — Enables precise stop positioning on form-fill-seal and cartoning lines where cycle time is critical.
- Crane & Hoist Applications — Dissipates regenerative energy during lowering operations, protecting the drive bus from overvoltage faults.
- Pump & Fan Systems — Reduces deceleration time on large-inertia loads where coast-to-stop is unacceptable.
- Machine Tool & CNC Auxiliaries — Supports fast E-stop sequences on spindle and axis drives paired with 1305 series inverters.
- Food & Beverage Processing — Meets hygiene-cycle timing requirements where abrupt, repeatable stops are mandated.

Why Engineers Specify This Model
- OEM-Matched Design — Factory-engineered to integrate directly with the 1305 drive chassis; no external resistor sizing or custom wiring harness required.
- Overvoltage Bus Protection — Clamps DC bus voltage during regenerative braking events, preventing nuisance F05 overvoltage faults and drive trips.
- Reduced Deceleration Time — Enables decel ramp times significantly shorter than coast-to-stop, improving throughput and process repeatability.
- Plug-In Installation — Designed for tool-minimal installation within the 1305 drive enclosure, reducing commissioning time on the plant floor.
- Proven Field Reliability — Part of Rockwell Automation’s validated accessory ecosystem with documented compatibility across 1305 drive variants.

Application-Specific FAQ
Q: Is the 1305-KBA09 compatible with all 1305 drive frame sizes?
A: The KBA09 kit is designed for specific frame sizes within the 1305 series. Always verify compatibility against your drive’s catalog number and the 1305 accessory compatibility matrix in Publication 1305-UM001 before ordering.
Q: Can I use an external braking resistor instead of this kit?
A: The 1305-KBA09 is a self-contained kit. For applications requiring higher braking duty cycles or extended braking periods, consult Rockwell Automation’s sizing guidelines — an external resistor with appropriate wattage rating may be required in addition to or instead of this kit.
Q: What fault codes does this kit help prevent?
A: Primarily F05 (DC Bus Overvoltage) faults that occur during rapid deceleration of high-inertia loads. It may also reduce nuisance trips on applications with frequent start/stop cycles.
Q: Is installation possible without a Rockwell-certified technician?
A: Installation should be performed by a qualified electrical engineer or technician familiar with drive systems and LOTO procedures. Konmask.com recommends consulting the official installation guide and local electrical codes.
Q: Do you provide a certificate of conformance (CoC)?
A: Yes, CoC documentation is available upon request for MRO, OEM, and government procurement orders. Contact us at the time of order.
