Overview
The Allen-Bradley 22B-D012N104 is a PowerFlex 40 adjustable frequency AC drive engineered for general-purpose motor control in industrial environments. Rated at 5.5 kW (7.5 HP) output power, this drive provides reliable speed and torque regulation for three-phase motors operating at 480 VAC. Equipped with sensorless vector control and integral PID functionality, the 22B-D012N104 delivers precise motion control for conveyor systems, pumps, fans, and other variable-speed applications without requiring external feedback devices.
Key Features
- Sensorless Vector Control: Delivers high starting torque and excellent speed regulation across the operating frequency range without external encoders or tachometers.
- Integral PID Control: Built-in proportional-integral-derivative algorithm enables closed-loop process control and stand-alone controller functionality.
- Embedded RS-485 Communication: Supports daisy-chain network connections (up to 32 drives per segment) and integrates with Modbus protocol for remote monitoring and diagnostics.
- Optional Multi-Protocol Support: Compatible with DeviceNet, EtherNet/IP, PROFIBUS, BACnet, and LonWorks communication modules for flexible network integration.
- Compact Panel-Mount Design: Frame Size C enclosure (IP20/NEMA Type Open) with integral digital keypad and LED display for local configuration and status monitoring.
- Industrial-Grade Protection: Internal IGBT brake mechanism, adjustable PWM frequency for EMI reduction, and relay pre-charge for extended component life.

Typical Applications
The 22B-D012N104 is designed for conveyor drive systems, centrifugal and reciprocating pumps, industrial fan and blower control, machine tool spindle drives, compressor speed regulation, and general-purpose OEM applications requiring robust variable-speed motor control. The sensorless vector control capability makes it ideal for applications demanding high starting torque, precise speed tracking, or energy efficiency optimization. Integral PID control supports process-loop regulation in material handling, fluid transfer, and precision manufacturing environments.
Compatibility & Replacements
The 22B-D012N104 belongs to the PowerFlex 40 family of adjustable frequency AC drives and integrates seamlessly with Rockwell Automation’s Logix platform (CompactLogix, ControlLogix, SoftLogix) via optional communication modules. The drive pairs with external branch-circuit protection devices such as the 140M-D8E-C20 circuit breaker and 100-C23 magnetic contactor. EtherNet/IP and Modbus connectivity enable integration with supervisory control systems and HMI platforms from multiple vendors.
End-of-Life Notice: The 22B-D012N104 is being phased out effective June 30, 2025. Rockwell Automation recommends migration to the 25B-D013N104 PowerFlex 755 drive for equivalent and enhanced functionality in new system designs.
