Product Introduction
Allen-Bradley 22C-D060A103 is a PowerFlex 400 AC drive for fan and pump applications. It runs on 480 V AC, 3-phase power and is rated at 40 HP with 60 A output current.
This drive is used when the system needs variable torque control, fixed keypad operation, and simple RS-485 communications. In replacement work, the key checks are motor nameplate current, enclosure fit, and whether the existing panel wiring matches the fixed terminal layout.

Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to This Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Drive does not power up | No line voltage or blown fuse | ✅ High | Measure 480 V AC at the input terminals and inspect upstream fusing | Check supply and fuses before replacing the drive |
| Motor does not run | Incorrect start command or control wiring | ✅ High | Verify start/stop input status and check the terminal block wiring | Confirm control logic and permissives |
| Overcurrent fault on start | Motor wiring error or locked rotor | ✅ High | Measure motor insulation and confirm U/V/W wiring | Verify motor and load before condemning the drive |
| RS-485 comms fail | Wrong baud rate or wiring polarity | ✅ High | Check A/B wiring and the drive communication settings | Match the master’s serial settings exactly |
| Drive trips on overload | Motor load too high or acceleration too short | ✅ High | Compare motor current to drive output current and review accel time | Reduce loading or lengthen acceleration |
| Panel overheats | Poor ventilation or undersized enclosure cooling | ✅ Medium | Measure cabinet temperature near the drive heatsink | Improve airflow and verify clearance |
If you are stuck, send the fault code, keypad photo, and wiring diagram to technical support.
Frequently Asked Questions
Q: What is 22C-D060A103?
A: It is an Allen-Bradley PowerFlex 400 AC drive rated for 480 V AC, 40 HP, and 60 A output current.
Q: Is this drive for constant torque or variable torque use?
A: PowerFlex 400 is aimed at fan and pump loads, so it is typically used where variable torque control is the right fit.
Q: Does it have a brake IGBT?
A: No. The listing indicates RS-485 without brake IGBT, so do not plan on dynamic braking unless your exact setup supports an external solution.
Q: Can I replace a different PowerFlex 400 code with this one?
A: Sometimes, but only if the voltage, horsepower, frame size, enclosure, and options match. The suffix matters more than people think.
Q: Is it hot-swappable?
A: No. Treat it like a live power conversion device. Isolate the cabinet and verify zero energy before removal.
Q: Why is it sold as New Surplus?
A: Because it is typically unused legacy stock. That usually means original inventory from excess or project closeout, not current factory production.
Q: What is the biggest installation mistake?
A: Skipping the motor nameplate check. If the motor current, voltage, or wiring scheme does not match the drive setup, you will chase nuisance trips fast.
