Overview
The Allen-Bradley 22B-D1P4N104 is a PowerFlex 40 adjustable frequency AC drive engineered for precision motor speed control in compact, space-constrained installations. This sensorless vector control (SVC/FOC) drive delivers 0.4 kW (0.5 HP) output power and operates across a 342-528 VAC input range, accommodating global voltage standards from 380-480V 3-phase systems. Its Frame B housing and IP20 rating make it ideal for panel-mount installations in protected industrial environments.
Key Features
- Sensorless Vector Control: Provides auto-boost and slip compensation for precise motor torque and speed without shaft feedback
- Integral Keypad Control: Built-in LCD display and potentiometer enable local Start/Stop/Jog/Frequency control without external devices
- RS-485 Communication: Native support for MODBUS and DeviceNet protocols; compatible with Drive Explorer and Drive Tool SP for PC-based programming and diagnostics
- Multiple I/O Options: 3 fixed START/STOP/REV inputs, 4 programmable discrete inputs, 1 NO/NC dry contact, 2 digital outputs, analog inputs (0-10V or 4-20mA), and analog output
- Compact Design: Frame B dimensions (3.94 × 12.6 × 5.35 inches) fit OEM equipment cabinets; no CE-compliant filter required for simpler integration
- Logix Platform Integration: Direct compatibility with Rockwell Automation ControlLogix and CompactLogix systems for unified parameter and tag programming
Technical Specifications
The 22B-D1P4N104 meets industrial UL/CSA and CE standards, making it suitable for machine tools, HVAC fans, centrifugal pumps, conveyors, and small material handling systems where space efficiency and ease of setup are critical.
Typical Applications
- Machine tool spindle and feed motor control
- HVAC fan and blower speed regulation
- Centrifugal pump flow control
- Conveyor and material handling belt drives
- Small OEM equipment requiring embedded motor speed control
Compatibility & Replacements
The 22B-D1P4N104 integrates seamlessly with Rockwell Automation’s Logix 5000 control platform and is compatible with EtherNet/IP, PROFIBUS, and LonWorks networks. It shares the PowerFlex 40 family architecture, making it functionally compatible with other Frame B models in the series. For larger motor applications, consider the 22B-D4P0N104 (2 HP, 1.5 kW) or 22B-D2P2N104 (1 HP, 0.75 kW) variants. Standard replacement cycle is 7–10 years; this used unit may be refurbished for legacy system repairs or OEM retrofit applications.
