ISO-certified repairs with a 2-year warranty — technician-verified quotes within 24 hours, nationwide.
Product Description
The Allen-Bradley 20DB4P2A3EYNA6NNA is a 240VAC, three-phase adjustable frequency AC drive with a NEMA Type 1/IP20 enclosure, suitable for 208V applications up to 4.8 amps. It features a user-friendly LCD, quick start guide, IGBT brake, adjustable undervoltage trip, microprocessor-controlled heat sink thermistor for overtemperature protection, and ride-thru capabilities of 0.25 seconds for logic control (drive not running) and 15 milliseconds for power at full load.
Is Your Device Showing These Signs?
The Allen Bradley 20DB4P2A3EYNA6NNA PowerFlex 755 AC drive commonly exhibits issues such as IGBT failures, capacitor degradation leading to DC bus undervoltage faults, and encoder feedback problems causing erratic motor control. Communication faults on the EtherNet/IP network are frequent, often stemming from corrupted firmware or misconfigured IP addresses. Overcurrent trips are addressed by inspecting motor insulation, drive parameters, and current sensors. Cooling fan malfunctions result in overheating and require immediate replacement to prevent thermal damage. Parameter corruption necessitates a firmware re-flash and drive re-configuration.

Our Repair Process for the
20DB4P2A3EYNA6NNA
Our repair process for the Allen Bradley 20DB4P2A3EYNA6NNA PowerFlex 755 AC drive begins with a comprehensive diagnostic evaluation to pinpoint the fault. IGBT failures are rectified through component replacement and rigorous testing. Capacitor degradation, indicated by DC bus undervoltage faults, requires capacitor replacement and DC bus stabilization. Encoder feedback problems are resolved by encoder repair or replacement, alongside meticulous signal verification. Communication faults on the EtherNet/IP network are addressed by firmware re-flashing and IP address reconfiguration. Overcurrent trips necessitate a thorough inspection of motor insulation, drive parameters, and current sensors, with faulty components replaced. Cooling fan malfunctions demand immediate fan replacement to prevent overheating. Parameter corruption is corrected by performing a firmware re-flash and complete drive reconfiguration to factory or user-defined settings.
