Detailed Product Overview
The Rexroth DKC02.3-100-7-FW acts as an intelligent processing node in high-precision motion control applications. By executing real-time current, velocity, and position control loops internally, the drive reduces computational overhead on the main machine controller while maintaining tight trajectory tracking and minimal settling times.
Communication with the master control architecture relies on the SERCOS interface standard, utilizing noise-immune fiber optic loops to transmit deterministic data across complex multi-axis setups. The 700 V DC-bus architecture allows rapid voltage scaling during high-acceleration transients, making it well-suited for heavy handling and high-inertia mechanical loads.
Housed in a compact panel-mount chassis, the unit integrates diagnostic display indicators and works alongside software configuration tools for parameter setup, gain tuning, and fault analysis.
