Description

The Allen-Bradley 22B-D4P0N104 is a 1.5 kW (2 HP) adjustable frequency AC drive from the PowerFlex 40 series, manufactured by Rockwell Automation. This compact drive delivers 4.0 A output current at 380-480V AC, three-phase input, making it suitable for speed and torque control of standard AC induction motors in light to medium industrial applications.

The drive features sensorless vector control technology, built-in RS485 communication, and an integral LED keypad for local programming. It is housed in a Frame B, IP20/NEMA UL Type Open enclosure and includes a built-in brake IGBT for dynamic braking applications. However, critical lifecycle notice: Rockwell Automation officially discontinued the PowerFlex 40 series as of June 30, 2025, with the 25B-D4P0N104 (PowerFlex 525 series) designated as the direct engineering replacement .

Application Scenarios

The 22B-D4P0N104 is designed for applications requiring reliable motor speed control in a compact footprint. Consider an OEM packaging machine builder who integrates this drive into a conveyor system for product sorting. The sensorless vector control provides high starting torque even at low speeds, ensuring smooth product transfer without jams or slippage. The built-in PID capability allows the drive to function as a standalone controller—directly accepting a 4-20mA pressure signal from a pump system to regulate motor speed without requiring an external PLC or PID controller .

In material handling applications, the 22B-D4P0N104 controls hoists, lifts, and conveyors with varying loads. The drive’s 150% overload capacity for 60 seconds handles temporary peak demands, while the flying start feature catches a spinning motor without tripping. The embedded RS485 port enables daisy-chained Modbus RTU networking, allowing multiple drives to be monitored and controlled from a central HMI or SCADA system. Flexible I/O includes 7 digital inputs (3 fixed for START/STOP/REV + 4 programmable) and 2 analog inputs, providing connectivity for limit switches, pushbuttons, and analog sensors .

For system integrators supporting installed equipment, the 22B-D4P0N104 serves as a direct drop-in replacement for existing PowerFlex 40 drives, minimizing downtime and re-engineering costs. However, given its End-of-Life status, careful inventory planning is recommended to maintain spares for critical production lines .
