Product Overview
The Allen Bradley 20BC8P7A0AYNANC0NNAD PowerFlex 700 AC Drive is a compact and high-performance Variable Frequency Drive (VFD) from the industry-leading PowerFlex 700 series developed by Rockwell Automation. Designed for demanding industrial automation applications, this AC drive provides precise motor speed regulation, advanced vector control, intelligent diagnostics, and comprehensive motor protection for a wide variety of three-phase AC induction motors.
Operating on a 380–480 VAC three-phase power supply, the 20BC8P7A0AYNANC0NNAD delivers a rated output current of 8.7 A, making it an ideal solution for small- and medium-power industrial equipment requiring accurate speed control, stable torque performance, and high energy efficiency. By continuously adjusting output voltage and frequency, the drive minimizes mechanical stress, reduces energy consumption, and improves overall system productivity.
This configuration features 24 VDC control I/O, sensorless vector control, no internal communication module, no Human Interface Module (blank cover), no brake IGBT, no internal braking resistor, and an integrated EMC filter with common-mode choke. Optional communication adapters such as EtherNet/IP, DeviceNet, ControlNet, PROFIBUS, or Modbus can be installed to support a wide range of industrial automation architectures.
With compact dimensions of 336 × 110 × 200 mm and an approximate weight of 5.22 kg, the drive is well suited for cabinet-mounted installations where installation space is limited while reliable performance remains essential.
Typical applications include conveyor systems, packaging machinery, pumps, fans, compressors, mixers, textile equipment, food and beverage processing machinery, HVAC systems, material handling equipment, woodworking machinery, and OEM automation systems.
