Overview
The Allen-Bradley 22B-D1P4N104 is a compact, cost-effective AC drive engineered for small-to-medium duty motor control. This PowerFlex 40 series drive combines proven sensorless vector control (SVC) with straightforward commissioning and local operational control via integral keypad. Operating at 380-480V AC, 3-phase input, it delivers 0.5 HP (0.4 kW) continuous output, making it ideal for OEM integrators and facilities seeking a space-saving, budget-conscious solution for enclosed panel installations.
Key Features
- Sensorless Vector Control (SVC): Delivers high-performance motor speed and torque control with auto-boost and slip compensation, enabling stable operation at 100% load synchronous speed and low-speed precision torque.
- Compact B-Frame Design: Reduces overall enclosure footprint while maintaining full functionality; ideal for tight panel-mount spaces in OEM machinery and control cabinets.
- Integral Keypad & LED Display: Local Start/Stop/Jog commands and frequency adjustment without external interface; status LEDs for quick operational diagnostics.
- RS-485 Serial Communication: Native ModBus protocol support for remote parameter adjustment, monitoring, and troubleshooting via Drive Explorer or Drive Tool SP software.
- Wide Input Voltage Range: 342-528 VAC tolerance accommodates global utility variations and transient voltage events, reducing nuisance trips and improving uptime.
- IP20 NEMA Type Open Enclosure: Panel-mount fixed terminal block design; integral cooling ensures thermal stability in continuous-duty industrial applications.
