The 22B-D012N104 belongs to the PowerFlex 40 family of compact AC drives, providing cost‑effective variable speed control for three‑phase induction motors in industrial and commercial applications. It accepts a 380–480 V AC, 3‑phase, 48–63 Hz supply (operating range 342–528 V AC) with an input current of about 14.2 A and kVA rating around 11.8 kVA, and delivers 5.5 kW (7.5 HP) motor power with 12.0 A continuous output current at 480 V, suitable for medium‑duty pump, fan and conveyor applications. The unit is supplied as Frame size C with an IP20 (Open), NEMA/UL Type Open panel‑mount enclosure and includes an internal brake IGBT for dynamic braking when used with an external brake resistor.
Control features include both V/Hz and sensorless vector control, allowing improved low‑speed torque and speed regulation compared with simple V/Hz drives. The output frequency is programmable from 0 to 400 Hz, and the drive offers built‑in process PID control, 8 preset speeds, and configurable acceleration/deceleration ramps, making it flexible for many applications. A built‑in RS‑485 communication port (Modbus/DSI) enables networking with other drives and PLCs, while the integral LED display and digital keypad provide straightforward local parameter setup and monitoring.
Rockwell Automation has announced that the 22B-D012N104 PowerFlex 40 5.5 kW (7.5 HP) AC drive is discontinued as of June 30, 2025, and recommends 25B-D013N104 PowerFlex 525 as the engineering replacement, but many users continue to deploy and maintain this model in existing systems. Typical uses include pumps, fans, blowers, small compressors, conveyors and material‑handling equipment where a compact 480 V, 7.5 HP VFD is required.
