Product Description
The Allen-Bradley 20BC85A0ANNANA0 PowerFlex 700 is a 45kW (85A, 400VAC, 3-phase, 50Hz) AC drive with a frame size of 4. It offers standard Allen-Bradley controls with 24V AC/DC I/O, 15ms power ride-through, and independently programmable acceleration/deceleration times (0-3600 seconds). It includes start/stop modes like Flying Start and S-curve, a blank HMI cover, no integral dynamic brake resistor/transistor, and supports 110% overload for 1 minute with a programmable current limit (20-160%). Featuring removable common mode capacitors and MOV for grounded/ungrounded systems, it supports droop control, shielded/unshielded cables, and external brake mechanisms (requiring separate brake protection).
Is Your Device Showing These Signs?
The Allen Bradley 20BC85A0ANNANA0 Servo Drive commonly experiences issues related to IGBT failures, often indicated by fault codes. Resolving this requires replacing the faulty IGBT module and thoroughly testing gate drive circuitry. Capacitor degradation within the power supply section is another frequent problem, leading to voltage instability and drive malfunction; replacing electrolytic capacitors restores proper operation. Encoder feedback errors, stemming from damaged encoder cables or faulty encoder modules, impede accurate motor control and necessitate cable replacement or encoder repair. Communication faults on the EtherNet/IP network are addressed by verifying network configurations, updating firmware, and inspecting physical connections to ensure seamless data transmission. Overcurrent trips, triggered by excessive motor load or short circuits, demand investigation of motor windings, load conditions, and drive parameters to prevent recurrence.

Our Repair Process for the
20BC85A0ANNANA0
Our repair process for the Allen Bradley 20BC85A0ANNANA0 Servo Drive begins with a comprehensive diagnostic assessment to pinpoint the root cause of the malfunction, focusing on common issues such as IGBT failures, capacitor degradation, encoder feedback errors, communication faults, and overcurrent trips. When IGBT failures are detected, the faulty module is replaced, and the gate drive circuitry is rigorously tested. Capacitor degradation is rectified by replacing all electrolytic capacitors within the power supply section. Encoder feedback errors are resolved through cable replacement or encoder module repair. Communication faults on the EtherNet/IP network are addressed by verifying network configurations, updating firmware, and inspecting all physical connections. Overcurrent trips necessitate a thorough investigation of motor windings, load conditions, and drive parameters, with corrective actions implemented to prevent future occurrences.
