Purchase now the 20DC037A0EYNANANK, a high-performance Variable Frequency Drive from the Allen-Bradley PowerFlex 700 series, designed for complex motor control at 400V.
What Is the 20DC037A0EYNANANK?
The 20DC037A0EYNANANK is a sophisticated AC drive engineered by Rockwell Automation to provide exceptional control for three-phase induction motors in demanding industrial environments. Rated at 37 Amps for 400V AC applications, this drive delivers approximately 18.5 kW (25 HP) of power. The PowerFlex 700 series is distinguished by its ability to handle both simple speed control and high-performance torque requirements. This specific model features an IP20 (NEMA Type 1) enclosure and the Vector Control package with 24V DC I/O, allowing for precise speed regulation and high starting torque. It is an ideal solution for applications such as coordinated web handling, lift systems, and high-torque extruders where precision and reliability are non-negotiable.

Industrial Compatibility and Network Architecture
The 20DC037A0EYNANANK is built on the DPI (Drive Peripheral Interface) platform, making it fully compatible with the 20-COMM series of communication adapters. This allow for seamless integration into EtherNet/IP, ControlNet, or DeviceNet architectures. The drive includes advanced features such as «Torque Proving,» which is vital for hoisting applications, and «Torque StepLogic» for basic positioning. Its rugged internal construction includes high-grade DC bus capacitors and a heavy-duty cooling system designed for continuous 24/7 operation in factory settings.
Installation Advice
When installing the 20DC037A0EYNANANK, it is vital to ensure proper grounding of the motor cable shield to the drive’s internal ground plate to minimize common-mode noise. For 18.5kW applications, always verify the ambient temperature inside the cabinet; if it exceeds 40°C, ensure active ventilation is optimized. Use the Connected Components Workbench software to perform an ‘Inertia Autotune’ during commissioning; this allows the drive to accurately model the mechanical load, resulting in much smoother acceleration and deceleration curves.
Frequently Asked Questions
Q: Does the 20DC037A0EYNANANK support encoder feedback?
A: Yes, this model supports various encoder feedback options via an optional encoder interface board, which is necessary for full closed-loop vector performance.
Q: Can I use this drive on a 480V network?
A: While rated for 400V, the PowerFlex 700 20D series typically has an allowable range up to 480V, but you must check the specific nameplate tolerance to avoid overvoltage faults.
