Overview
The Allen-Bradley 22B-D2P3N104 PowerFlex 40 AC drive delivers cost-effective, variable-frequency motor control in a compact package. Rated at 0.75 kW (1 HP) with 480VAC 3-phase input and 2.3 Amps continuous output, this drive is engineered for OEMs, machine builders, and end users requiring flexible speed control without the cost or complexity of larger drive families. The PowerFlex 40 series combines essential protection, integrated programming, and space-saving design—making it ideal for retrofit and original equipment applications.
Key Features
- Sensorless Vector Control: Delivers robust low-speed torque performance and precise speed regulation without encoder feedback.
- Integrated LCD Keypad: Built-in digital display and control interface enable parameter programming and status monitoring without external software or remote modules.
- Configurable I/O: Three fixed and four fully programmable discrete inputs; two digital/optocoupler outputs and one N.O./N.C. relay output; two unipolar and one bipolar analog inputs; one analog output.
- Integral PID Loop: Closed-loop process control for tension, flow, pressure, and other proportional-integral-derivative feedback applications.
- Overload & Thermal Protection: Drive-level protection against sustained overload, ramp regulation, and flying-start capability for seamless restarts.
- Communication & Integration: RS485 serial interface; compatible with Logix control platforms for simplified parameter and tag programming via Allen-Bradley studio environments.
