Product Description
The Allen-Bradley 20AD052A0NYNACCN is a PowerFlex 70 series IP20 panel-mounted AC drive (E Frame) designed for diverse applications like extruders and fans. It delivers 52 Amps and 40 HP output at 480VAC (50Hz, 3-phase). With single-phase input, output current derates to 50%, resulting in input ratings of 47.4 Amps and 12.8 kVA, and output ratings of 26 Amps and 40/30 HP (normal/heavy-duty). Single-phase operation allows for short-term overloads of 30 Amps (1 minute) and 40 Amps (3 seconds). This drive lacks an HMI and internal brake resistor but includes a ControlNet interface (coaxial cable) and brake IGBT. It supports enhanced control (no safe torque off). Operating temperature is 32-122F, storage is -40-158F. Dimensions are 555.8 x 280.3 x 207.1 mm, weight is approximately 18.60 kg. Vertical mounting in a non-corrosive environment with 76mm top/bottom clearance is required for proper cooling. A drive manual is sold separately.
Is Your Device Showing These Signs?
The Allen Bradley 20AD052A0NYNACCN AC drive commonly experiences failures related to the electrolytic capacitors degrading, causing DC bus undervoltage faults and erratic operation. IGBT failures are frequent due to overcurrent events or thermal stress, resulting in drive trips and potential damage to the motor. The control board is susceptible to damage from power surges or electrical noise, leading to communication errors or complete failure of the drive. Encoder feedback issues, stemming from faulty wiring or a damaged encoder interface, cause speed regulation problems and inaccurate positioning. Cooling fan malfunctions contribute to overheating, accelerating component degradation and triggering thermal overload faults.
Technical specifications
The Allen-Bradley 20AD052A0NYNACCN is a PowerFlex 70 AC drive (E Frame) for panel mounting, suitable for applications like extruders and fans. It outputs 52A/40HP at 480VAC (3-phase). Single-phase input derates output to 26A/40-30HP (normal/heavy-duty) with specific overload capabilities. It lacks an HMI and internal brake resistor but features a ControlNet interface and brake IGBT, supporting enhanced control. It requires vertical mounting with specific clearances in a non-corrosive environment and has defined operating/storage temperatures, dimensions, and weight. The drive manual is sold separately.
Our Repair Process for the
20AD052A0NYNACCN
Our repair process for the Allen Bradley 20AD052A0NYNACCN AC drive begins with a comprehensive evaluation to pinpoint the root cause of the failure. Electrolytic capacitors are tested for degradation and replaced without exception. IGBTs are thoroughly inspected and replaced if any signs of overcurrent or thermal stress are present. The control board undergoes rigorous testing, and damaged components are replaced or the entire board is replaced as needed. Encoder feedback circuits and wiring are meticulously checked and repaired, with encoder replacement performed if necessary. The cooling fan is inspected and replaced to ensure proper thermal management. Following component replacement, the drive undergoes extensive testing under load to verify proper operation and adherence to factory specifications.
