22A-B4P5N104 | Allen-Bradley PowerFlex 4 AC Drive 240VAC 3PH 4.5A 0.75kW 1HP IP20

The 22A-B4P5N104 is a variable frequency drive (VFD) designed to control the speed and torque of three-phase AC motors. It modulates motor speed by adjusting the output frequency and voltage. This model is commonly used in applications such as pumps, fans, and conveyors where precise speed control improves energy efficiency and process accuracy. The drive supports sensorless vector control for enhanced performance. It is part of the PowerFlex 4 series, intended for compact and low-horsepower installations.

The drive supports Volts/Hertz (V/Hz) control and Sensorless Vector Control (SVC). These methods allow for flexible operation depending on the application requirements. V/Hz control is suitable for constant torque loads, while SVC offers better dynamic performance without feedback devices. The drive also includes basic acceleration and deceleration ramps. With programmable control inputs and analog reference capabilities, it can adapt to different motor control schemes.

This VFD allows speed control via keypad, analog input (0–10 V or 4–20 mA), or digital commands. It supports frequency references and programmable acceleration/deceleration ramps. The speed regulation is within ±2% over a 40:1 speed range. Speed feedback is not required thanks to sensorless vector control. This ensures responsive motor performance even without encoders. Speed can also be changed dynamically via external control signals.

The drive can be mounted on a DIN rail or directly on a panel using screws. Its compact design simplifies installation in confined spaces. The mounting process is tool-friendly and requires minimal effort. It is critical to provide proper ventilation and maintain spacing from heat-generating components. The ambient operating temperature range is -10 to 50°C. Proper installation ensures long-term reliability and thermal performance.

No, the 22A-B4P5N104 is currently in its End of Life (EOL) phase and will be officially discontinued as of June 30, 2025. After this date, it will no longer be available for sale through Rockwell Automation. Customers are advised to begin transitioning to the designated replacement product, which is the 25A-B5P0N104 from the PowerFlex 525 series. The successor offers more advanced features, including enhanced communication capabilities and safety functions. For existing installations, support and documentation are still available during the phase-out period, but future system designs should avoid using the discontinued model.
