Product Description
The Allen-Bradley 20DJ156A3ENNA1CNK is a 600V three-phase adjustable frequency AC drive from Rockwell Automation, featuring a 156 amp input, NEMA Type 1 compliant IP20 enclosure, full numeric LCD for configuration, quick start guide, adjustable bus undervoltage trip, heat sink thermistor with overtemperature protection, 0.25-second logic ride-thru, and 15-millisecond full load power sustain, but lacks a braking feature.
Is Your Device Showing These Signs?
The Allen Bradley 20DJ156A3ENNA1CNK servo drive commonly experiences issues related to power stage failures, often indicated by fault codes stemming from overcurrent or overvoltage events. Resolve these faults by inspecting and replacing damaged IGBTs or MOSFETs within the inverter section. Communication errors on the EtherNet/IP network are frequently traced to corrupted firmware, necessitating a firmware update or, in severe cases, a complete drive reflash. Encoder feedback problems, manifesting as erratic motor behavior, demand thorough examination of the encoder cable and replacement of the encoder itself if signal degradation persists. Overheating issues arise from inadequate cooling, requiring inspection and cleaning of the heatsink and fan assembly to ensure proper thermal dissipation.

Our Repair Process for the
20DJ156A3ENNA1CNK
Our repair process for the Allen Bradley 20DJ156A3ENNA1CNK servo drive begins with a comprehensive fault code analysis to pinpoint the failure area. Power stage failures, indicated by overcurrent or overvoltage faults, are addressed through inspection and replacement of faulty IGBTs or MOSFETs in the inverter section. Communication errors on the EtherNet/IP network are resolved by updating the firmware or performing a complete drive reflash if corruption is present. Encoder feedback problems, identified by erratic motor behavior, require a detailed examination of the encoder cable and replacement of the encoder if signal degradation continues. Overheating issues are rectified by inspecting and cleaning the heatsink and fan assembly to restore proper thermal dissipation.
