Product Description
The Allen-Bradley PowerFlex 700S AC drive, part number 20DJ125A3NNNACNNN, is a 600V, three-phase, 125-amp unit with an IP20/NEMA Type 1 enclosure for indoor use, featuring a full numeric LCD for user interaction, adjustable bus undervoltage trip, microprocessor-monitored heat sink thermistor for overheat protection, 0.25-second logic control ride-thru, and 15-millisecond power ride-thru at full load, but lacks integrated braking.
Is Your Device Showing These Signs?
The Allen Bradley 20DJ125A3NNNACNNN AC drive commonly experiences issues such as blown power semiconductors (IGBTs), capacitor failures within the DC bus, and encoder feedback problems leading to erratic motor control. Overcurrent faults and overvoltage faults are frequent due to improper motor tuning or line power fluctuations. Communication errors on the Ethernet/IP network and parameter corruption within the drive's memory also occur, necessitating firmware updates or parameter resets. Repair often involves replacing damaged components, recalibrating drive parameters, and thoroughly testing the motor-drive system under load to ensure proper operation and prevent future failures.
Technical specifications
The Allen-Bradley PowerFlex 700S AC drive (20DJ125A3NNNACNNN) is a 600V, 125A, three-phase drive designed for indoor use (IP20/NEMA Type 1). It has a numeric LCD, adjustable undervoltage trip, heat sink overheat protection, and short ride-thru capabilities for both logic control and power, but does not include integrated braking.
Our Repair Process for the
20DJ125A3NNNACNNN
Our repair process for the Allen Bradley 20DJ125A3NNNACNNN AC drive begins with a comprehensive diagnostic evaluation to pinpoint the root cause of the reported issues, which commonly include failed IGBTs, DC bus capacitor failures, or encoder feedback problems. Technicians replace all damaged components, including power semiconductors, capacitors, and encoder modules, with new, high-quality replacements. The DC bus is reformed, and all drive parameters are recalibrated to factory specifications or application-specific requirements. Firmware is updated to the latest revision to address known bugs and improve performance. The motor-drive system undergoes rigorous testing under load to verify proper operation, confirm accurate motor control, and prevent recurrence of overcurrent, overvoltage, or communication faults before the unit is returned.
