Allen-Bradley 22A-A8P0N114 PowerFlex 4 Drive: Specifications and Replacement Guide

The 22A-A8P0N114 is an Allen-Bradley PowerFlex 4 adjustable-frequency AC drive designed for basic motor speed control in industrial equipment. It operates from a 240V-class single-phase supply and provides an 8.0A rated output for a 1.5 kW (2 HP) motor application. The drive includes an integrated EMC filter, RS485 communication, an LED display, and a fixed digital keypad.

Rockwell Automation discontinued this model on June 30, 2025, and identifies the PowerFlex 523 25A-A8P0N114 as its engineering replacement. That makes accurate specification matching particularly important for maintenance teams purchasing spares or upgrading installed equipment.

This guide examines the electrical ratings, control features, common applications, and replacement requirements of the 22A-A8P0N114, with a focus on avoiding compatibility problems during procurement and installation.

Buyers seeking the original drive can view the Allen-Bradley PowerFlex 4 product details and quotation options before preparing a replacement or spare-parts order.

What Are the Key 22A-A8P0N114 Specifications?

The 22A-A8P0N114 belongs to the PowerFlex 4 family, a compact range of AC drives intended for straightforward variable-speed applications.

According to the official Rockwell Automation PowerFlex 4 product documentation, the drive provides the following specifications:

These specifications establish the drive’s basic electrical and installation requirements, but they do not prove that it is suitable for every 1.5 kW motor.

Motor full-load current, starting characteristics, mechanical loading, and the available supply must be checked before installation.

For replacement work, the complete catalog number is especially important. Other PowerFlex 4 drives may share the same nominal power rating while using different input configurations or filtering options.

How Does the 22A-A8P0N114 Control Motor Speed?

The 22A-A8P0N114 controls the speed of a compatible AC motor by adjusting the frequency and voltage supplied to the motor.

The PowerFlex 4 family uses volts-per-hertz (V/Hz) motor control, making it suitable for applications where adjustable speed is required without the complexity of precision servo positioning.

Three features are particularly relevant to an existing installation.

1. Single-Phase Input With Three-Phase Motor Output

The drive accepts a 240V-class single-phase AC supply and generates a variable-frequency three-phase output for a compatible motor.

This arrangement can be useful in workshops and smaller industrial installations where a suitable three-phase mains supply is unavailable.

However, the drive does not make every three-phase motor compatible with single-phase power.

The motor voltage rating, full-load current, wiring arrangement, and operating load still determine whether the drive can operate the motor correctly.

2. Integrated RS485 Communication

The 22A-A8P0N114 includes an RS485 communication interface for communication with compatible controllers or automation equipment.

This can allow motor control and monitoring functions to be incorporated into a wider machine control system.

Before replacing the drive, engineers should record the existing communication configuration, including:

• Network address and communication settings
• Controller communication protocol
• Start and stop command source
• Speed reference source
• Relevant control parameters

The physical presence of an RS485 interface does not guarantee communication compatibility with every controller or replacement drive.

3. Integrated EMC Filter and Braking IGBT

The internal EMC filter helps address conducted electromagnetic interference when the drive is installed according to the applicable wiring, grounding, and EMC requirements.

The integrated brake IGBT also supports dynamic braking arrangements when correctly configured with an appropriate external braking resistor.

The resistor is not automatically included merely because the drive contains a braking transistor.

For applications involving rapid deceleration or high-inertia loads, braking requirements should be verified using the PowerFlex 4 AC Drive User Manual.

Where Is the 22A-A8P0N114 Commonly Used?

With an 8.0A output rating and compact panel-mounted construction, the 22A-A8P0N114 is suited to relatively small motor-driven systems requiring adjustable speed.

Typical applications include:

Conveyor Systems

Small conveyors often require speed adjustment to coordinate material movement with upstream or downstream equipment.

The drive can provide variable-frequency motor control, provided starting torque and continuous motor current remain within the acceptable operating range.

Industrial Fans and Blowers

Ventilation systems may use adjustable motor speed to manage airflow instead of relying entirely on mechanical restriction.

Actual energy savings depend on the fan characteristic, operating profile, and system design.

Pumps

Variable-speed operation can help match pump output to changing process requirements.

Pump selection must account for motor characteristics, minimum operating speed, cooling, and hydraulic conditions.

Packaging Equipment

Packaging machinery may require adjustable speed for conveyors, feeders, or auxiliary rotating components.

The PowerFlex 4 can be appropriate for basic speed control, but applications requiring tightly controlled positioning or synchronized motion generally need a different control architecture.

General Industrial Machinery

The drive can also be considered for mixers and other small rotating equipment when their starting load, acceleration requirements, and duty cycle are compatible with its capabilities.

For any application, the 1.5 kW rating should be treated as an initial sizing reference rather than a guarantee of performance.

Why Was the 22A-A8P0N114 Discontinued?

Rockwell Automation lists the 22A-A8P0N114 as discontinued effective June 30, 2025.

Discontinuation means the original model is no longer offered for new sales by the manufacturer. It does not automatically mean every installed drive must be replaced immediately.

Many industrial facilities continue operating equipment containing discontinued AC drives.

The difficulty usually appears when a unit fails or maintenance personnel need an identical spare.

At that point, procurement teams may need to consider existing distributor inventory, surplus stock, professionally refurbished equipment, or an engineering replacement.

The main concern is not simply whether a drive can be located. It is whether the supplied unit matches the electrical configuration and condition required by the machine.

A replacement purchased under an incorrect suffix may create additional installation work, even when its nominal motor power rating appears identical.

22A-A8P0N114 vs 25A-A8P0N114: What Is the Difference?

Rockwell Automation identifies the PowerFlex 523 engineering replacement drive as the recommended alternative for the discontinued 22A-A8P0N114.

The two drives share several important electrical ratings, but this should not be interpreted as unrestricted plug-and-play compatibility.

Both models have an 8.0A output rating and are intended for similar motor power classes.

However, an engineering replacement can require changes to the wiring, mechanical installation, control parameters, or communication configuration.

Electrical Compatibility

Check the actual input supply voltage and phase arrangement against the replacement drive’s requirements.

The motor nameplate current must also be verified, especially if the original motor has been changed since the equipment was commissioned.

Mechanical Compatibility

Frame B identification does not establish that the two drives have identical dimensions, terminal positions, or mounting-hole arrangements.

Before purchasing the 25A-A8P0N114, compare the manufacturers’ dimensional drawings and confirm that the existing control cabinet provides adequate space and ventilation.

Control and Parameter Compatibility

PowerFlex 4 and PowerFlex 523 belong to different drive generations.

Existing speed references, terminal assignments, control logic, and operating parameters must be reviewed during the migration.

A previously saved PowerFlex 4 parameter list should be used as an engineering reference, not assumed to be directly transferable to the PowerFlex 523.

Communication Compatibility

Where the original drive communicates with a PLC or supervisory controller, verify the replacement’s supported protocol, addressing, wiring, and register or parameter mappings.

The correct replacement procedure depends on how the machine was originally integrated.

What Should Engineers Check Before Replacing a 22A-A8P0N114?

Replacement work should begin with the installed drive, not only the new supplier quotation.

The following checks help prevent avoidable commissioning problems.

If the original drive is still operational, maintenance personnel should record its parameter settings before removal.

These settings may include motor nameplate data, minimum and maximum frequency, acceleration time, deceleration time, control source, and communication parameters.

For machinery containing interlocks or safety-related control functions, the replacement should also be evaluated against the existing safety design.

A successful motor rotation test does not, by itself, confirm that the complete machine has been correctly recommissioned.

How to Buy a Discontinued 22A-A8P0N114 Drive

Purchasing a discontinued AC drive requires more verification than ordering a current-production component.

A seller may describe a unit as new, used, surplus, or refurbished. These conditions represent different levels of uncertainty.

Before ordering, buyers should request:

1. The complete catalog number and nameplate photographs.
2. Confirmation of the unit’s physical and operational condition.
3. Available testing records or inspection information.
4. Serial number and relevant hardware revision details.
5. Confirmation of included accessories and keypad condition.
6. Current stock availability and estimated dispatch time.
7. Warranty and return terms.

New old stock may be suitable for maintaining an existing installation, but storage history and condition should still be considered.

A refurbished drive may also be usable when the supplier can explain the refurbishment scope and testing performed.

For facilities operating multiple PowerFlex 4 drives, maintaining a documented spare-parts strategy can reduce the risk of prolonged equipment downtime.

Industrial automation buyers looking for obsolete drives, spare parts, or replacement components can check the available PowerFlex 4 drive listing at SieSource and request information about the specific model, available condition, and quotation options.

Stock availability, pricing, and lead time should be confirmed for each request rather than assumed.
