Product Description
The Allen-Bradley PowerFlex 700S series 20DJ460N0NNNB1CSL is a 650V DC adjustable frequency AC drive designed for demanding motor control, delivering up to 460 amps in normal duty. Its IP00-rated open enclosure requires careful placement to avoid environmental exposure, and it features a blank HMI cover. While documentation is not included, it offers adjustable bus undervoltage trip, microprocessor-controlled overtemp protection via a heat sink thermistor, 0.25-second ride-thru during non-operation, and 15-millisecond full-load ride-thru for stable performance during power fluctuations, making it suitable for precision and safety-critical motor control applications.
Is Your Device Showing These Signs?
The Allen Bradley 20DJ460N0NNNB1CSL servo drive commonly experiences issues such as IGBT failures, capacitor degradation leading to DC bus undervoltage faults, and resolver feedback errors causing positioning inaccuracies. Overcurrent trips are frequent due to motor winding shorts or excessive load. Communication faults on the Ethernet/IP network and corrupted firmware necessitate troubleshooting and potential replacement. Power supply failures within the drive module are also a typical problem, requiring component-level repair or full unit replacement.
