With B&R ACOPOSmulti, all drive modules work together. A power supply module provides the common DC bus, distributed via the mounting plate rail to the inverter modules that each drive one or two axes, and an auxiliary supply module completes the system if necessary. Repairing a sub-assembly of this architecture therefore raises a simple question: how can you prove it works once it is alone on the workbench?
Our answer is a B&R Automation ACOPOSmulti test bench built in our workshop in Crac’h, Morbihan. The automated testing program was developed in-house by our technician Yoann GUEZEL. Every repair goes through it: diagnosis, testing, and validation before being returned to the customer.
We work on all sub-assemblies in the ACOPOSmulti family

- 8BVP — active power supply modules
- 8B0P — passive power supply modules
- 8BVI — inverter modules, single and dual-axis
- 8B0C — auxiliary power supply modules

We perform component-level repairs rather than standard exchanges: this allows us to address the root cause of a failure rather than simply displacing it. This expertise is at the heart of our drive and servo drive repair service, for all brands.
Why a Test Bench Changes the Repair Process
Without a test bench, a power electronics repair is limited to static measurements. The customer only discovers the actual result on their machine during production. With a dedicated bench, the repaired module is put back into situational use in the workshop under reproducible conditions from one intervention to the next. What is sent back is no longer a repair assumed to be good; it is a verified repair.
What This Means for Your Maintenance
Because ACOPOSmulti modules share the same DC bus, a single faulty sub-assembly can bring the entire machine to a standstill. A module repaired and validated on a test bench means a restart without waiting for new supplies, controlled ownership costs over time, and an electronic assembly that does not end up as WEEE waste.
⚠️ Safety — DC Bus
A drive module retains dangerous energy in its DC bus capacitors long after the power supply has been cut. Any intervention requires the lockout/tagout of the installation, compliance with the discharge time specified by the manufacturer, and a verification of the absence of voltage. If in doubt, do not dismantle anything: entrust the sub-assembly to a professional.
Beyond ACOPOSmulti: Other B&R Sub-assemblies
Our workshop also repairs other B&R Automation sub-assemblies: servo drives from the ACOPOS P3 range, for which we have also built a dedicated test bench, PLCs, as well as HMI screens and panels. If your equipment is no longer repairable or if you want to secure a critical stock, our shop for tested reconditioned equipment can also provide a solution.
