• Product Overview
• 

DKC11.1‑040‑7‑FW belongs to Rexroth DKC series servo drive system. It delivers high‑performance closed‑loop control for synchronous servo motors, widely adopted in machine‑tool, printing and metal‑processing automation equipment. SERCOS digital bus supports high‑speed real‑time communication with upper‑level controller. Multiple built‑in fault‑protection functions secure drive and motor during abnormal conditions. Discontinued servo drive unit is supplied as refurbished and new‑old‑stock spare parts for production‑line equipment overhaul.

Application Notes

‑ Reserve enough cooling clearance around drive unit inside ventilation cabinet. ‑ Match drive power rating with servo‑motor nameplate data. ‑ Disconnect three‑phase AC power and discharge DC‑bus before servicing. ‑ Typical deployment: machine tools, printing machinery, automated assembly‑line spare‑part stocking.
