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 warrantyEen proces gebouwd rond vertrouwen
Ontvangst & inspectie
Your drive arrives, gets logged under its own case reference, and goes through a full visual and electrical check before any power is applied.
Diagnose & offerte
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.
Repareren, testen & terugsturen
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
Traceerbaarheid
A unique case reference and a full repair report follow your drive from the moment it arrives.
Load-tested
Every repaired drive is run under load — not just powered on — before it leaves the workshop.
Inzicht in de oorzaak
When a drive keeps tripping, we dig into why — motor, cabling, or the drive itself — and flag it in the report.
Garantie
Reparaties are backed by a standard warranty, so you're covered once the drive is back on the machine.
Repareren of vervangen?
Kies reparatie wanneer
- 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
- Je hebt een traceerbare reparatie nodig met een rapport en garantie
Overweeg vervanging wanneer
- 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
Zorg dat het op de juiste manier bij ons komt
- 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.
- Schrijf de zaakreferentie op zowel de drive als de doos.
- Beschrijf de fout: uitschakelcodes, wanneer het gebeurt en onder welke belastingconditie.
- Gebruik antistatische bescherming en pak het zo in dat encoderconnectors geen impact kunnen krijgen.
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.
