Overview
The Allen-Bradley 22B-D2P3N104 is a compact PowerFlex 40 variable-frequency AC drive designed for general-purpose motor control in industrial automation. This Frame B unit accepts 480V 3-phase AC input (342–528V nominal range) and delivers 0.75 kW (1 HP) motor output at 2.3 A. With sensorless vector control, integral LED keypad, and embedded RS-485 communication, it enables precise speed and torque regulation for small to medium industrial machinery.
Key Features
- Sensorless Vector Control: Delivers excellent low-speed torque and speed regulation without encoder feedback.
- Integral LED Display & Keypad: Fast out-of-the-box configuration and real-time monitoring without external devices.
- Built-in Brake IGBT: Enables cost-effective dynamic braking for safe controlled stops.
- RS-485 Communication: Supports multi-drop network integration and MODBUS RTU protocol (03/06 commands).
- Robust Overload Protection: Flying start, ramp regulation, and removable MOV for grounded/ungrounded system compatibility.
- Adjustable PWM Frequency: Configurable switching for quiet or high-efficiency operation.

Typical Applications
The Allen-Bradley 22B-D2P3N104 excels in compact, standalone machine-level motor control:
- Pump & fan speed control (HVAC, water handling)
- Conveyor drive systems & material handling
- Mixer & agitator applications
- Machine-tool spindle drives
- Energy-saving retrofits for constant-speed motors
- Process-based speed adjustment (tension, flow, pressure)
Compatibility & Replacements
The 22B-D2P3N104 integrates seamlessly with Rockwell Automation control platforms via Connected Components Workbench (CCW) software for advanced parameter management. It supports standard DeviceNet, EtherNet/IP, and PROFIBUS protocols through optional serial converter modules. Drop-in replacement for other 1 HP 480V frame-B PowerFlex drives; consult Rockwell technical documentation (Part TD-22-TD001) for wiring and commissioning details. Used units are commonly available as refurbished inventory from authorized distributors and surplus suppliers.
