Product Description
The Allen-Bradley 20G11ND361JN0NNNNN is a PowerFlex 755 AC drive, designed for high performance and flexibility up to 2000 HP. It utilizes DeviceLogix control technology, features a built-in Ethernet interface, and is KCC, CE, and ABS certified. This specific model accepts 342-528 VAC input, delivering 300 HP output at 480 VAC nominal input with a continuous current of 361 Amps. Input over-voltage trip is at 576 VAC and under-voltage trip at 300 VAC, with a nominal motor voltage of 460 VAC. It lacks an integrated HMI but supports optional modules. It includes a filter and CM cap jumper, but no internal resistor or transistor. Housed in an IP00 open NEMA/UL enclosure (frame-7) measuring 34.7 x 16.93 x 8.19 inches and weighing approximately 106 kg, it operates in ambient temperatures of 32-104F and storage temperatures of -40 to 158F, with a non-condensing relative humidity of 5-95% in a non-corrosive environment.
Is Your Device Showing These Signs?
The Allen Bradley 20G11ND361JN0NNNNN PowerFlex 755 AC drive commonly experiences issues such as IGBT failures, DC bus capacitor degradation leading to over-voltage faults, and control board corruption causing communication errors on EtherNet/IP networks. Resolving nuisance tripping due to improper motor parameter settings and addressing excessive heat buildup from inadequate cooling fan operation are frequent repairs. Firmware upgrades are required to mitigate software bugs and ensure compatibility with newer control systems. Correcting ground faults stemming from insulation breakdown within the drive or motor windings is essential for operational stability.
