DIAGNOSTICS & SYMPTOMS

Common VFD & Motor Drive Faults We Fix

  • Drive completely dead or no output voltage to motor terminals
  • Overcurrent (OC), overvoltage (OV), or ground fault trips
  • Control panel / display unlit despite main line power present
  • Blown IGBT modules, bridge rectifiers, or main DC bus capacitors
  • Erratic speed regulation or motor stuttering from drive faults
  • Fieldbus/communication board failures (Modbus, Profibus, RS485)
  • Control board damage caused by lightning strikes or grid surges
  • Trips linked to internal cooling fan or thermal sensor failures

TRANSPARENT WORKFLOW

Our Industrial VFD Repair Process

1. Fault Isolation

Static and dynamic bench testing to isolate power stage, driver, or control board failures.

2. Quote

Upfront commercial estimate for your approval before we proceed with the actual repair

3. Repair

Component replacement, including power semiconductors, optocouplers, etc

4. Load Testing

Bench testing under simulated load conditions to confirm waveform and thermal stability.

5. Handover

Unit returned with a full technical repair summary for your maintenance records.

Why Board-Level Drive Repair?

A VFD failure is rarely a total loss โ€” usually it stems from a single shorted IGBT, a blown gate driver IC, or a failed sensor circuit. Replacing entire industrial drives can take weeks of import delays and cost thousands. We repair directly down to the board level, minimizing costly operational downtime while keeping repair budgets manageable.

Brands & Turnaround Times

We service major industrial brands including Danfoss, ABB, Schneider Electric, Siemens, Yaskawa, Vacon, Delta, and Fuji Electric.

Priority bench diagnosis is available for critical production faults. Initial findings are usually provided within 24โ€“48 hours depending on drive physical size and fault complexity.
