Product Description
The Allen-Bradley 20DJ460N3NNNBRANE AC drive, designed for reliable industrial performance, operates at 650V DC and handles up to 460 amps for demanding applications. Its IP00-rated open design features a full numeric LCD for easy monitoring and control, adjustable undervoltage trip for safety, microprocessor-controlled heat sink thermistor for overtemperature protection, and ride-thru capabilities (0.25 seconds logic control, 15 milliseconds power) to maintain stability during power disturbances; however, it lacks a braking mechanism.
Is Your Device Showing These Signs?
The Allen Bradley 20DJ460N3NNNBRANE commonly experiences issues related to failed IGBTs, capacitor degradation within the DC bus, and resolver feedback malfunctions. Over time, thermal stress degrades the electrolytic capacitors, leading to DC bus undervoltage faults and drive trips. Furthermore, the IGBTs are prone to failure due to overcurrent events or thermal runaway, necessitating replacement. Resolver signal errors, caused by wiring issues or faulty resolver components, disrupt accurate motor control and position feedback, requiring thorough diagnostics and potential resolver replacement or cable repair.

Our Repair Process for the
20DJ460N3NNNBRANE
Our repair process for the Allen Bradley 20DJ460N3NNNBRANE begins with a comprehensive evaluation to pinpoint the failure. This evaluation includes rigorous testing of the IGBTs, DC bus capacitors, and resolver feedback system. Failed IGBTs are immediately replaced with new, high-quality components. Degraded DC bus capacitors are replaced to restore proper voltage levels and prevent future undervoltage faults. Resolver signal errors are addressed through meticulous inspection of wiring and resolver components; faulty resolvers are replaced, and wiring issues are corrected. Post-repair, the drive undergoes extensive testing under load conditions to ensure optimal performance and reliability before it is returned.
