Purchase now the 20AC3P5A0AYNANC0, a high-efficiency PowerFlex 70 adjustable frequency AC drive designed for seamless integration into 400V industrial networks.
What Is the 20AC3P5A0AYNANC0?
The 20AC3P5A0AYNANC0 is a compact and versatile Variable Frequency Drive (VFD) from the Allen-Bradley PowerFlex 70 family, engineered by Rockwell Automation. This specific model provides 3.5 Amps of output current, delivering approximately 1.5 kW (2.0 HP) of power for three-phase induction motors. The PowerFlex 70 is renowned for its «A-frame» architecture which optimizes panel space while providing advanced motor control features like Sensorless Vector Control and Volts per Hertz regulation. The 20AC3P5A0AYNANC0 comes with an IP20 (NEMA Type 1) enclosure and a blank cover, making it an ideal choice for centralized control cabinets where the drive is managed via remote communication or a PLC interface without the need for a local HMI.

Industrial Architecture and Modulation
The 20AC3P5A0AYNANC0 architecture is designed for high-performance applications such as small centrifugal pumps, industrial fans, and packaging conveyor systems. It utilizes a Pulse Width Modulation (PWM) signal with a programmable carrier frequency to minimize motor acoustic noise and optimize energy consumption. Despite its small size, it supports advanced features like «Flying Start,» which allows the drive to catch a rotating load without tripping, and «StepLogic,» which acts as a built-in position sequencer for basic indexing tasks. Its integration into the Allen-Bradley Logix environment via optional 20-COMM adapters ensures high-speed data exchange and simplified maintenance routines.
Expert Tips
When deploying the 20AC3P5A0AYNANC0 in environments with high electrical noise, ensure that the motor cable is shielded and that the shield is grounded 360 degrees at the drive’s ground plate. This is critical for 1.5kW drives as they are often placed near sensitive low-voltage sensor wiring. Additionally, since this model features a blank cover, use the Connected Components Workbench (CCW) software to perform an ‘Autotune’ during commissioning to perfectly match the drive to the motor’s specific impedance, maximizing torque at low speeds.
Frequently Asked Questions
Q: Does the 20AC3P5A0AYNANC0 include an internal communication port?
A: Yes, it features the Drive Peripheral Interface (DPI) which allows you to plug in various 20-COMM modules for Ethernet, ControlNet, or DeviceNet connectivity.
Q: Can I use this drive on a single-phase 230V supply?
A: No, the 20AC series is specifically designed for 3-phase 400V/480V input. Using a single-phase supply will result in an undervoltage fault or hardware damage.
