Servo drive repair, tested under real load
From nuisance overcurrent trips to a drive that won't power up at all, we repair AC servo drives at component level — then run each unit under load before it ships back, not just a bench power-on test.
Every drive gets a reference, a report and a warrantyUn processus construit autour de la confiance
Réception et inspection
Your drive arrives, gets logged under its own case reference, and goes through a full visual and electrical check before any power is applied.
Diagnostic & devis
We trace the fault to the failed component — power stage, control board or feedback circuit — and send a clear quote. Nothing gets repaired until you approve.
Réparation, test & retour
Once approved, we repair the drive and run it under simulated or dyno load before shipping it back with a full report.
Common servo drive faults
- Power module (IGBT) failure or shorted output stage
- Blown gate driver circuits after a motor or cable fault
- Encoder or resolver feedback loss and position errors
- DC bus capacitor degradation and undervoltage trips
- Recurring overcurrent or overvoltage fault loops
- EtherCAT, Profibus or SSCNET communication faults
- Cooling fan failure and thermal shutdowns
- Corrupted or lost parameter sets after a fault event
Repair happens at component level, so an obsolete drive model or one the manufacturer no longer supports doesn't automatically mean replacement.

What every servo drive repair includes
Traçabilité
A unique case reference and a full repair report follow your drive from the moment it arrives.
Testé en charge
Every repaired drive is run under load — not just powered on — before it leaves the workshop.
Analyse de la cause profonde
When a drive keeps tripping, we dig into why — motor, cabling, or the drive itself — and flag it in the report.
Garantie
Réparations are backed by a standard warranty, so you're covered once the drive is back on the machine.
Réparer ou remplacer ?
Choisissez la réparation lorsque
- The exact drive model is discontinued or hard to source
- You need existing tuning and parameter sets preserved
- A retrofit to a new drive generation isn't planned yet
- Vous avez besoin d'une réparation traçable avec un rapport et une garantie
Envisagez le remplacement lorsque
- You need the axis running now and a matched spare is ready
- A motion system retrofit is already planned
- The new drive generation needs a different feedback protocol anyway
Envoyez-le de la bonne manière
- Photograph the nameplate, connectors and any visible damage before you pack it up.
- Note the matched motor model, if known — it helps us verify feedback compatibility.
- Écrivez la référence de cas à la fois sur le variateur et sur la boîte.
- Décrivez la panne : codes de déclenchement, quand cela se produit et dans quelles conditions de charge.
- Utilisez une protection antistatique et emballez-le de manière à ce que les connecteurs d'encodeur ne puissent pas subir d'impact.
When the fault only shows up on the machine
Some servo faults only appear under real load, coupling, or wiring conditions a bench test can't reproduce. When that's the case, we can send an engineer to you instead.
