PowerFlex 4M 0.4 kW (0.5 Hp) AC Drive 22F-A2P5N103 22FA2P5N103 22F-A2P5N103

Allen-Bradley 22F-A2P5N103 | PowerFlex 4M 0.4 kW / 0.5 HP — 1-Phase 200–240V In / 3-Phase Out / Frame A / RS-485

Single-Phase In, Three-Phase Out

The 22F-A2P5N103 converts a standard single-phase 200–240V supply into variable-frequency three-phase output to drive a conventional three-phase AC induction motor. For OEM machine builders who need to ship globally, this single-phase input removes a significant constraint — three-phase supply is not universally available, but single-phase is. The motor connected to the output should be a standard three-phase AC induction motor rated 0.4 kW / 200–230V. Do not connect a single-phase motor — the drive's output is three-phase.

The output frequency range extends to 400 Hz, covering both below-base speed operation (0 to 50/60 Hz with full torque) and above-base speed field weakening. Acceleration and deceleration times are independently adjustable from 0 to 600 seconds in 0.1-second increments.

What the Catalog Number Says

The N filter code means no built-in EMC filter. For EN 61800-3 compliance (required in EU regulated markets), an external 22F-RF series filter must be added at the input. The 0 brake code means no dynamic braking capability — for high-inertia loads requiring fast deceleration, this drive is not appropriate.

Key Specifications

Integral I/O — No External PLC Needed for Basic Control

The drive carries 5 × 24V DC discrete inputs (sink/source configurable via DIP switch), 1 × 0–10V DC analog input, 1 × 4–20 mA analog input, and 1 × Form C relay output. For basic speed control from a panel, the drive operates completely standalone from the integral 4-digit LED keypad with no external controller.

For PLC-integrated systems, the 4–20 mA or 0–10V analog input accepts a speed reference directly, and the discrete inputs connect to PLC digital outputs for start, stop, and direction commands. Integral RS-485/DSI enables Modbus RTU communication with MicroLogix, SLC 500, and ControlLogix platforms.

Frame A Dimensions and Mounting

Frame A is the smallest PowerFlex 4M form factor. Zero-stacking (side-by-side with no gap) is permitted at ambient temperatures up to 40°C. Above 40°C up to 50°C, minimum spacing between drives applies. Both DIN rail and panel mounting are supported. DIN rail installation simplifies assembly and field replacement.

FAQ

Q1: Does the connected motor also need to be single-phase?

No. Connect a standard three-phase AC induction motor rated 0.4 kW / 200–230V. The drive converts the single-phase input to three-phase output internally. Single-phase motors are not designed to run from a three-phase variable-frequency output and should not be used.

Q2: Is an EMC filter needed, and how is one added?

The N variant has no integral filter. For EN 61800-3 compliance in regulated markets, an external 22F-RF series filter must be added at the input wiring. For unregulated industrial environments where EMC compliance is not required, the drive operates normally without one.

Q3: Can the 22F-A2P5N103 connect to a PLC for speed and control commands?

Yes. The analog inputs (0–10V or 4–20 mA) accept speed reference from a PLC analog output. The five discrete inputs accept sinking or sourcing 24V DC digital signals for start, stop, direction, and preset speeds. Integral RS-485/DSI enables Modbus RTU communication with Allen-Bradley and compatible PLCs. No additional signal conditioning hardware is needed in most configurations.

Q4: What happens if the load decelerates too quickly without a brake transistor?

Without a brake IGBT, regenerated energy from a decelerating high-inertia load raises the DC bus voltage, tripping the drive on F005 (bus overvoltage). For most small 0.4 kW applications — conveyors, small fans, pumps — the load inertia is low enough that this is not a practical issue. If the application requires fast stops on higher-inertia loads, consider PowerFlex 4M Frame C variants with integral brake transistors.

Q5: What is the difference between 22F-A2P5N103 and 22F-B2P5N103?

Both are 0.4 kW / 0.5 HP Frame A PowerFlex 4M drives with identical output specifications. The input differs: A = 200–240V AC single-phase; B = 200–240V AC three-phase. Where three-phase input is available, the B-prefix variant is preferred — it draws lower current per conductor and produces less harmonic distortion. The A-prefix exists specifically for locations where only single-phase supply is accessible.
