Product Description
The Allen-Bradley PowerFlex 70 series drive, model 20AD027F0AYNANC0, is an air-cooled, three-phase 480VAC drive rated for 27 Amps, delivering 20 HP in normal duty and 15 HP in heavy-duty applications. It features an IP20 NEMA Type 1 front enclosure and a NEMA Type 4X/12 rear enclosure with conformal coating for indoor/outdoor use. Equipped with 6 digital inputs, 2 relay outputs, 2 analog inputs, and 1 analog output, this drive lacks an integrated HMI but supports an LCD screen and programmable keypad for easy programming in industrial environments. It includes a Brake IGBT but requires an external brake resistor. Motor control options include Volts/Hertz, sensorless Vector Control, and Vector Control with FORCE Technology, supporting both speed and torque control with or without encoder feedback, as well as positioning indexing and speed profiling. Parameter linking functionality, a Second Environment Filter (CE compliant), DriveGuard Safe Torque, and pump/traverse capabilities for fiber applications are included. The drive facilitates plant-wide communication via EtherNet/IP, DeviceNet, ControlNet, and other networks, offering lower programming and installation costs compared to alternatives.
Is Your Device Showing These Signs?
The Allen Bradley 20AD027F0AYNANC0 AC drive commonly experiences failures related to the electrolytic capacitors degrading, resulting in DC bus undervoltage faults and nuisance tripping. IGBT failures are frequent due to overcurrent events or thermal stress, necessitating replacement to restore proper motor control. The cooling fan's malfunction causes overheating, triggering thermal overload protection and requiring immediate attention. Corrupted firmware leads to erratic behavior, resolved by reflashing the correct software version. Communication errors on the Ethernet/IP network are traced to faulty network interface cards or configuration issues, demanding troubleshooting and potential hardware replacement.

Our Repair Process for the
20AD027F0AYNANC0
Our repair process for the Allen Bradley 20AD027F0AYNANC0 AC drive begins with a comprehensive diagnostic evaluation to pinpoint the failure. Electrolytic capacitors are tested for degradation and replaced to eliminate DC bus undervoltage faults. IGBTs are inspected; replacements are installed to correct overcurrent events or thermal stress damage. The cooling fan's functionality is verified, and a replacement is performed to prevent overheating. Firmware is checked for corruption, and the correct software version is reflashed to resolve erratic behavior. Ethernet/IP network communication is analyzed, faulty network interface cards are replaced, and configuration issues are corrected to ensure proper network operation.
