Overview
The Allen-Bradley 22B-E1P7N104 is a PowerFlex 40 variable frequency drive engineered for cost-effective motor speed control in compact industrial installations. Rated at 0.75 kW (1 HP), this drive delivers precise three-phase motor regulation in a frame B enclosure with open IP20 protection and built-in digital keypad control. As one of the smallest members of the PowerFlex family, it combines space savings, ease of use, and reliable performance for OEM and end-user applications.
Key Features
- Sensorless Vector Control: Advanced motor control providing excellent speed regulation and high starting torque without feedback devices
- Robust Overload Protection: Rated for 150% load acceleration with microprocessor-controlled overcurrent limits
- 8 Preset Speed Settings: Flexible speed profile selection for varying application requirements
- 4 Programmable Digital Inputs: Fully configurable I/O for custom control logic and automation integration
- RS485 Communication: Native serial port with support for DeviceNet, EtherNet/IP, and MODBUS protocols
- Compact Frame B Design: Space-saving construction ideal for tight panel and outdoor enclosure mounting
Technical Specifications
Input: 600 Volt AC, 3-phase, 50–60 Hz. Output: 0.75 kW (1 HP) at 1.7 A continuous. Control: Sensorless vector mode with PWM output frequency adjustable for quiet operation. Enclosure: IP20 open-style frame, NEMA/UL Type Open, panel-mount configuration. Connectivity: Built-in RS485 serial port; optional communication cards available (Profibus, BACnet, LonWorks). No integrated filter—external L-type filter (part 22-RF8P0-BL) required for CE compliance. Operator interface: Digital keypad with LED display and reset button. Acceleration/Deceleration: Four independently programmable ramps from 0 to 600 seconds in 0.1-second increments. Thermal: Operating range –10 to +50°C (14 to 122°F). Storage range –40 to +85°C (–40 to 185°F) at 5–95% relative humidity.
Typical Applications
- Machine tool spindle speed control
- Fan and blower motor regulation
- Pump speed modulation for flow control
- Conveyor belt drive acceleration/deceleration
- Material handling system motor control
- General-purpose variable speed industrial applications
Compatibility & Replacements
The 22B-E1P7N104 integrates with Allen-Bradley CompactLogix and ControlLogix platforms via EtherNet/IP or serial gateway. Programming is performed using Studio 5000 Logix Designer with native PowerFlex object templates. Logix5000 controllers provide seamless tag-based parameter access and real-time fault diagnostics. Note: This model is discontinued as of June 30, 2025, with engineering replacement 25B-E1P7N104 recommended for new installations. Used units remain suitable for retrofit, maintenance, and OEM repair applications. No manufacturer filter is included; ensure external filter compliance for CE markets.
