Product Description
The PowerFlex 700H AC drive (20CD300A0AYNBNB0), rated for 480 VAC, is a 3-phase, 300 Amp drive offering 250 HP peak power for normal duty and 200 HP for heavy-duty applications. Designed for straightforward operation with standard control and 120V I/O, it features a Brake IGBT but lacks a common mode choke, communication module, feedback, and a drive-mounted brake resistor. Housed in a Type 1/IP21 enclosure, it includes a second environment filter compliant with CE EMC Directive (89/336/EEC) for suitable environmental performance.
Is Your Device Showing These Signs?
The Allen Bradley 20CD300A0AYNBNB0 AC drive commonly experiences issues such as IGBT failures, capacitor degradation leading to DC bus undervoltage faults, and encoder feedback problems causing erratic motor control. Resolving these faults requires replacing damaged power components, reforming or swapping DC bus capacitors to restore proper voltage levels, and troubleshooting/replacing the encoder or its wiring to ensure accurate speed and position feedback. Parameter corruption within the drive's memory also occurs, necessitating a firmware reload and configuration. Overcurrent trips are addressed by inspecting the motor and wiring for insulation breakdown or shorts.
