PowerFlex 4 Drive Wiring and Terminal Connections
Correct wiring is necessary for reliable operation of the 22A-B012N104. The drive includes separate terminals for incoming AC power, motor output, grounding, and control signals.
Power Wiring Connections
| Terminal | Function |
|---|---|
| R/L1 | Three-phase AC input |
| S/L2 | Three-phase AC input |
| T/L3 | Three-phase AC input |
| U/T1 | Motor output phase U |
| V/T2 | Motor output phase V |
| W/T3 | Motor output phase W |
| PE / Ground | Protective earth connection |
The three-phase supply connects to the input terminals, while the motor connects to the output terminals.
Power wiring must follow the applicable Rockwell Automation documentation, including the required grounding, protection, conductor sizing, and installation procedures.

Control Wiring and Communication
The PowerFlex 4 series supports several motor control arrangements, including:
- Digital inputs for start, stop, and direction commands.
- Analog speed reference signals.
- Local control through the integrated keypad.
- RS485 communication for supported industrial control configurations.
Control terminal assignments and operating functions depend on the configured parameters.
Before replacing a drive, technicians should record the existing wiring arrangement and parameter settings to avoid unexpected changes in motor behavior.
Motor Compatibility and Industrial Applications
The Allen-Bradley 22A-B012N104 is suitable for appropriately rated three-phase induction motors requiring variable speed control.
Typical applications include:
Conveyor Systems: Adjusting conveyor speed to match production requirements and material handling processes.
Pumps and Fans: Controlling motor speed in compatible pumping and ventilation systems.
Packaging Machinery: Managing motor acceleration and operating speed in packaging equipment.
Industrial Production Lines: Supporting adjustable-speed motor control in manufacturing and processing machinery.
Application suitability depends on the motor’s electrical ratings, load torque, duty cycle, and environmental conditions.
Available Models and Specifications
The PowerFlex 4 series includes several models with different power and current ratings.
| Model Number | Motor Power | Output Current | Input Supply |
|---|---|---|---|
| 22A-B1P5N104 | 0.2 kW / 0.25 HP | 1.5 A | 200–240V, 3-phase |
| 22A-B2P3N104 | 0.4 kW / 0.5 HP | 2.3 A | 200–240V, 3-phase |

The model ratings are based on Rockwell Automation’s PowerFlex technical documentation.
Although these models belong to the same product family, they are not automatically interchangeable. Motor current, frame dimensions, protection settings, and existing control wiring must be considered.
22A-B012N104 Replacement and Compatibility
Rockwell Automation discontinued the 22A-B012N104 on June 30, 2025, and identifies the 25A-B011N104 as an engineering replacement.
An engineering replacement should not be treated as a direct drop-in substitute without reviewing the installation.
Before ordering a replacement, verify:
- Complete drive catalog number and nameplate.
- Motor rated voltage, current, and power.
- Existing power and control wiring.
- Communication requirements and parameter configuration.
- Panel mounting dimensions and environmental conditions.
For existing installations, sourcing the original model may reduce the changes required, provided the unit’s condition and suitability are confirmed.
