Allen-Bradley 1305-KBA09 ডাইনামিক ব্রেক
The 1305-KBA09 is an external dynamic brake assembly for Bulletin 1305 drives, providing a resistive path for excess regenerated motor energy during deceleration.
Product Overview
Technical Specifications
Technical identification and operating characteristics of the 1305-KBA09 dynamic brake assembly.
Additional Dimensions, Fuse and Electrical Details
Dynamic Braking Operation
During deceleration, a motor can regenerate electrical energy and return it to the drive DC bus. If the returned energy raises bus voltage beyond the permitted level, the drive may generate an overvoltage trip.
Compatibility & Important Restrictions
Drive Configuration
- Manufacturer's listed application: 460 V AC, 5 HP (4.0 kW).
- Confirm the drive series and actual motor/load braking requirements before replacement.
- The brake's peak assembly rating is 3.4 kW; average braking power and duty cycle must also remain within the manufacturer's limits.
- Drive parameter P.011 (DB Enable) must be set to Enable when dynamic braking is installed.
Installation & Operating Requirements
Mounting Conditions
- Install the brake enclosure in the vertical position only.
- Mount outside other enclosures or cabinets with unrestricted circulating air.
- Maintain at least 304.8 mm (12 in) clearance from the drive and other enclosures.
- Keep the brake within 30 m (100 ft) of the drive.
Electrical Safety
- Remove all power before installation or maintenance.
- Allow at least 60 seconds after removing input power for the DC bus to discharge.
- Use the manufacturer's specified fuse type and rating.
- Repeated fuse failure requires replacement of the brake assembly; the manufacturer states that the brake is not repairable.
Applications & Failure Scenarios
Where the 1305-KBA09 Is Used
The unit is used alongside compatible Bulletin 1305 AC drives in motor applications that require additional dynamic braking during deceleration and ramp-to-stop operations.
Typical sourcing situation: Maintenance teams may search for this brake assembly when a 1305 drive develops recurring overvoltage trips during deceleration, when the braking function is unavailable, or when the installed braking assembly requires replacement.
Potential downtime impact: Unresolved braking problems can interrupt motor stopping sequences, cause drive trips and prevent production equipment from completing its operating cycle. The actual impact depends on the machine and its stopping requirements.
Frequently Asked Questions
1. What is the Allen-Bradley 1305-KBA09 used for?
It is a dynamic brake assembly used with compatible Bulletin 1305 drives to dissipate excess regenerated motor energy during deceleration and help prevent DC bus overvoltage.
2. Can the 1305-KBA09 be installed on a Series A 1305 drive?
No. Rockwell Automation specifically restricts this model to Series B and later drives. Using it with Series A equipment can cause component damage or drive failure.
3. What is the peak braking power rating of the 1305-KBA09?
The manufacturer's installation instructions list a peak brake assembly rating of 3.4 kW for this model. Average power and duty cycle must also be checked against the published operating limits.
4. What should be checked when the 1305-KBA09 stops operating?
Check the drive and braking configuration, internal fuse condition, installation environment and thermostat-related operating conditions. The manufacturer specifies that the brake assembly is not repairable and should be replaced if its fuse blows repeatedly.
