Product Overview

6SE7031‑7EE85‑0AA0 belongs to Siemens SIMOVERT MASTERDRIVES vector‑control family, a regenerative common‑bus rectifier unit for multi‑drive groups in heavy‑industry applications such as metal rolling mills, cranes, test‑stands and extrudersMade-in-Ch…. Instead of dissipating braking energy via brake resistors, it returns regenerative power back to the AC mains network to improve overall system energy efficiency. Equipped with CUR control electronics and PMU local operator panel for parameter setup and fault diagnosis. End‑of‑life drive hardware available as refurbished and tested surplus spare unit for legacy multi‑drive system overhaul projects.

Application Notes

‑ Install inside well‑ventilated electrical cabinet; maintain specified clearance for cooling air flow. ‑ Discharge DC‑bus capacitors completely before opening unit cover for service work. ‑ Match DC‑bus voltage rating to connected inverter modules. ‑ Typical deployment: steel‑plant multi‑drive group rectifier‑unit spare‑part stocking.
