Product Description
The Allen-Bradley PowerFlex 755 series 20G11BD960JN2NNNNN drive is a highly efficient, 480VAC/650VDC unit designed for diverse industrial applications, accepting AC voltage with DC terminals and featuring precharge. Its IP20/NEMA/UL Type 1 rated enclosure (600mm deep, RAL 7032) ensures reliable, code-compliant operation. Signal integrity is enhanced via filtering, and a jumper-connected common mode capacitor simplifies installation. The absence of internal resistors and transistors streamlines the design, making it a robust and practical choice.
Is Your Device Showing These Signs?
The Allen Bradley 20G11BD960JN2NNNNN PowerFlex 755 AC drive commonly experiences issues related to IGBT failures, capacitor degradation within the DC bus, and encoder feedback malfunctions. Resolving these problems involves replacing faulty IGBT modules, swapping out deteriorated DC bus capacitors to maintain proper voltage regulation, and recalibrating or substituting defective encoder components to ensure accurate motor control. Parameter corruption within the drive's memory and communication faults on the EtherNet/IP network are also addressed through firmware updates and network configuration adjustments. Overcurrent faults and ground faults are investigated by inspecting motor insulation and power wiring.

Our Repair Process for the
20G11BD960JN2NNNNN
Our repair process for the Allen Bradley 20G11BD960JN2NNNNN PowerFlex 755 AC drive begins with a comprehensive diagnostic evaluation to pinpoint the root cause of the reported issue. IGBT failures are rectified through the replacement of the defective IGBT module with a new, tested component. Capacitor degradation within the DC bus is resolved by exchanging the deteriorated capacitors to restore optimal voltage regulation. Encoder feedback malfunctions are corrected via recalibration or component replacement to guarantee precise motor control. Parameter corruption requires firmware updates to restore proper drive operation, and communication faults on the EtherNet/IP network are addressed through meticulous network configuration adjustments. Overcurrent and ground faults necessitate a thorough inspection of motor insulation and power wiring to identify and eliminate any shorts or grounding issues.
