Product Description
The Allen-Bradley 20BB260A0ANNANC0 is a 3-phase AC drive (208-240V, 260A) with a 100 HP regular duty output and an IP20/Model 1 enclosure featuring a conformal coating. It lacks an HMI, Brake IGBT, and communication module, but includes a drive-mounted brake resistor and a second environment filter compliant with the CE EMC directive. It offers vector regulation with 24V I/O (no feedback) and supports various horsepower ratings (0.25-50, 0.25-100, and 0.5-75 HP) and output voltage ranges (200-240V, 500-600V, 500-690V, and 380-480V AC), with output voltage ranging from 0V to the input voltage. Enclosure options include IP20 NEMA/UL Type 1, IP54 NEMA 12, and Open/flange. It operates optimally at 400 Hz with a frequency tolerance of 47-63 Hz and features user-friendly design elements like easy wiring, quick disconnect, a pull-apart regulation terminal block, internal communication options, brake transistors, integral EMC filters, and common mode functionality for space-saving.
Is Your Device Showing These Signs?
The Allen Bradley 20BB260A0ANNANC0 PowerFlex 755 AC drive commonly experiences failures related to the DC bus capacitors, IGBT module degradation, and cooling fan malfunctions, all of which lead to over-voltage, over-current, or thermal faults. Resolving communication errors on the Ethernet/IP network and addressing issues with the control board, such as firmware corruption or component failure, are typical repairs. Furthermore, current sensor drift and encoder feedback problems cause inaccurate motor control, necessitating calibration or replacement. Damage from electrical surges and environmental contamination also require immediate attention to prevent catastrophic failure.

Our Repair Process for the
20BB260A0ANNANC0
Our repair process for the Allen Bradley 20BB260A0ANNANC0 PowerFlex 755 AC drive begins with a comprehensive diagnostic evaluation to pinpoint the failure. We address common issues such as DC bus capacitor failures, IGBT module degradation, and cooling fan malfunctions by replacing components with new, high-quality parts. Communication errors on the Ethernet/IP network and control board issues, including firmware corruption, are resolved through reprogramming or component-level repair. Current sensor drift and encoder feedback problems are corrected with precise calibration or replacement. We also repair damage from electrical surges and environmental contamination by cleaning, resealing, and replacing damaged components to restore the drive to optimal operational condition.
