22A-A2P3F104 PowerFlex 4 Allen-Bradley AC Drive, 0.5 HP

22A-A2P3F104: Small Drive, Simple Job

The 22A-A2P3F104 is a PowerFlex 4 AC drive from Allen-Bradley. It runs a 0.4 kW (0.5 HP) motor on single-phase 200…240V AC power. A flange mount keeps the heatsink outside the panel.

This unit gives 2.3 A output with open-loop control. A built-in keypad and LED screen make setup quick. The RS-485 DSI port speaks Modbus RTU. An integral brake IGBT handles stopping. No EMC filter is inside, so plan the filter for CE work.

Decode the Part Number

• 22A
  • A
    • 2P3
      • F
        • 1
          • 0
            • 4

22A means PowerFlex 4. A sets 240V one-phase input. 2P3 marks 2.3 A and 0.5 HP. F means flange mount. 1 is the fixed keypad. 0 means no filter. 4 is the standard build.

Inputs, Outputs and Control

No encoder input exists. This is open-loop control only. No Safe Torque Off is published. Use a contactor for safety stops.

Network and Serial

• Built-in port: one RS-485 DSI
• Protocol: Modbus RTU, function codes 03, 06 and 16
• Nodes: 1…247; add repeaters past 32

No Ethernet port exists. No option-card slot is listed. Serial is the only built-in network.

Mount and Wire

• Fit the drive through the panel cutout, heatsink outside.
• Keep the drive side at -10…50 °C.
• Hold heatsink air at -10…40 °C.
• Keep humidity below 95 %, non-condensing.
• Use a 10 A branch fuse.
• Add a 140M motor protector or 100-C contactor.
• Fit the 22-RF010-AL L-type filter for CE.
• Add a brake resistor of at least 60 Ω for fast stops.
• Limit motor cable to 10 m with a filter.

Convection cools this flange build. No fan runs inside the panel side. No corrosive gas, vapor or dust may reach the unit.

Setup and Service

• Set PWM frequency with parameter A091, default 4 kHz.
• Set node address with A104 and baud with A103.
• Set frame format with A107, default 8-N-1.
• Read faults on the LED display.
• Add a remote keypad with 22-HIM-C2 or 22-HIM-A3.
• Use 22-HIM-H10 or 22-HIM-H30 DSI cables.
• Add the 22-JBAA kit for IP30 protection.

FAQ

Can I run this drive on three-phase power?

No. This build takes one-phase 200…240V only. Choose a three-phase model for that supply.

Does this drive close a position loop?

No. It has no encoder port. It runs open-loop with slip compensation.

What brake resistor should I pick?

Use 60 Ω or higher. The AK-R2-091P500 fits a 5 % duty cycle.

How long can the motor cable be?

Ten meters with a filter in most settings. One meter in unrestricted Class B setups.

From shop floor experience, what trips these units first?

Loose control terminals and dusty heatsinks. Tighten screws and clean fins on every service visit.

Can I talk to it from a PLC?

Yes, over Modbus RTU. Use function codes 03, 06 and 16 on the RS-485 port.
