INTRODUCTION & KEY CHALLENGES fa Safety first. A drive's DC bus remains charged for several minutes after power is cut: its capacitors can retain a lethal voltage. Never open a live drive. Lock out the system, wait for discharge, and verify the absence of voltage...

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...

A B&R ACOPOS P3 servo drive fault can bring an entire production line to a standstill. To diagnose, test, and validate our repairs for this range, we have built our own test bench in our workshop in Crac’h, Morbihan. An internally developed test bench The test...

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....
