The SEW MoviDrive Modular Movi-C range is a modular drive architecture: a power supply module feeds a shared DC bus, to which axis modules are connected. Repairing a sub-assembly from this range therefore raises a simple yet daunting question: how can you verify that it works, once it is alone on the workbench and separated from its machine?
Our answer lies in a test bench that we designed and assembled in our workshop in Crac’h. It was set up in-house by our technician Yoann Guezel. It enables us to diagnose, test, and validate every repair on this range before the equipment is returned to the customer.
The SEW MoviDrive Modular Movi-C sub-assemblies we repair
The bench covers the three module types in the range:
- MDP90A — power supply modules
- MDA90A — single-axis modules
- MDD90A — dual-axis modules
We carry out component-level repairs, not standard exchange: this is the only approach that addresses the root cause of a failure rather than shifting it elsewhere. This expertise is at the heart of our drive and servo drive repair service, across all brands.
Why a test bench changes the nature of the repair
Without a test bench, a power electronics repair
ends with a static check: measurements are correct, the replaced components are compliant, and the unit is sent back in hope. The customer discovers the result on their machine, in production.
With a dedicated bench, the sequence is reversed. The repaired sub-assembly is put back into operating conditions in the workshop, under reproducible conditions identical from one job to the next. What leaves is no longer a repair assumed to be good; it is a verified repair. For a maintenance team, the difference is measured in hours of avoided downtime and in restarts that do not turn into a second incident.
What This Means for Your Maintenance
An axis module put back into service means an axis running again and a machine returning to its pace. It also means an electronic assembly that does not end up as WEEE: for this type of equipment, repair is the most direct lever for extending the service life of industrial assets. The issue is not only the equipment itself, but the availability of the production tool and the total cost of ownership over time.
⚠️ Safety — DC bus
A drive module retains dangerous energy in the capacitors of its DC bus long after the power supply has been switched off. Any work requires lockout/tagout of the installation, compliance with the discharge time specified by the manufacturer, and verification of absence of voltage. If in doubt, do not dismantle anything: entrust the sub-assembly to a professional.
Beyond Movi-C: other SEW sub-assemblies
Our workshop also handles other SEW-EURODRIVE sub-assemblies—operator displays and interfaces, drives and servo drives from other ranges. Industrial displays and HMIs, like industrial electronic boards, follow the same logic: component-level diagnosis, repair, and testing before return.
If your equipment can no longer be repaired, or if you are looking to secure a critical stock, our shop of tested refurbished equipment can also be a solution.
