Get now the 20AC8P7A0AYNANC0, a powerful 8.7 Amp PowerFlex 70 drive designed for heavy-duty 4.0kW motor control and energy-intensive industrial processes.
What Is the 20AC8P7A0AYNANC0?
The 20AC8P7A0AYNANC0 represents a mid-range power solution in the Allen-Bradley PowerFlex 70 series for 400V class applications. Engineered by Rockwell Automation, this 8.7A drive provides 4.0 kW (5.0 HP) of output, making it suitable for larger industrial machinery like compressors, vertical lifts, and medium-sized material handling systems. The PowerFlex 70 series is highly regarded for its balance of power and compactness. This specific part number includes an IP20 (NEMA 1) enclosure and a blank cover, optimized for systems where all control is handled via an industrial network. It provides top-tier motor control through its Force Technology or Sensorless Vector modes, ensuring high precision in speed regulation even under fluctuating loads.

Advanced Power Management and Safety
The 20AC8P7A0AYNANC0 is built to handle the electrical stresses of a 4.0kW load. Its internal DC bus is supported by long-life capacitors and a robust bridge rectifier. The drive includes sophisticated protection algorithms, such as «Bus Regulated Deceleration,» which automatically adjusts the deceleration rate to prevent DC bus overvoltage faults without needing an external resistor for moderate loads. For safety-critical environments, this model’s Enhanced Control allows for the integration of safety protocols when paired with the correct communication or safety-rated auxiliary components, providing a scalable solution for complex machine safety requirements.
Maintenance Tips
For a 4.0kW drive like the 20AC8P7A0AYNANC0, periodic inspection of the internal cooling fans is essential. At this power level, fan failure can lead to an overtemperature shutdown during peak production hours. We recommend using a vacuum to remove any dust from the heatsink fins every six months. Also, it is vital to verify the tightness of the power terminal screws, as thermal cycling can eventually lead to loose connections. Use the internal diagnostic logs to monitor the «DC Bus Voltage» and «Output Current» peaks to identify motor or mechanical issues before they cause a system failure.
Frequently Asked Questions
Q: Is the 20AC8P7A0AYNANC0 compatible with permanent magnet motors?
A: Yes, with the Enhanced Control option, this drive can be configured to control permanent magnet motors, though a firmware check is recommended for specific motor models.
Q: What is the benefit of the ‘Enhanced Control’ package in this model?
A: Enhanced Control provides higher precision for torque loops and allows the drive to perform more complex logic tasks and better synchronization with other PowerFlex drives via the DPI port.
