Stages of Repairing Allen Bradley PowerFlex Drives

Stage 1:
Diagnosis

The first step involves identifying the issue with the Allen Bradley PowerFlex VFD, whether it’s the PowerFlex 525, PowerFlex 755, or another model. This may involve checking error codes, running diagnostic software, and inspecting physical components.

Stage 2:
Component Testing

After diagnosis, specific components such as capacitors, transistors, and power modules are tested to pinpoint the faulty part.

Stage 3:
Repair or Replacement

Faulty components are either repaired or replaced. For instance, an Allen Bradley PowerFlex 70 may require a new IGBT module, while an Allen Bradley PowerFlex 40 might need a capacitor replacement.

Stage 4:
Reassembly and Testing

Once repairs are made, the drive is reassembled and thoroughly tested under simulated operating conditions to ensure it’s functioning correctly.

Stage 5:
Final Calibration & Installation

The repaired drive is calibrated to the required specifications and then reinstalled in its application, ready to resume its role in the production process.

Common Repairs with VFDs

Like all devices, variable frequency drives have occasional operational issues that sometimes require attention. Luckily, these common problems have relatively simple solutions:

Contamination

Contamination from dust, dirt, moisture and corrosion buildup can damage cooling fans and induce overheating, which can cause fault tripping and premature drive failure. Try cleaning off any contaminants that may impact performance.

Loose wiring

Changing cycle temperatures can cause wire connections to loosen over time, resulting in overcurrent trips and control issues. Make sure your wires are tight and secure.

Erratic operation

If your VFD is functioning erratically but no fault has been indicated, external factors like burned, cracked or overheated components could be the cause. Be sure to replace any defective parts to improve operation.
