Product Overview
The Schneider Electric MC-4/11/03/400 is a compact, all-in-one servo controller and drive unit designed to control a single axis of motion in high-performance industrial automation systems. It belongs to Schneider’s Lexium PacDrive product family and is specifically engineered to deliver precise, synchronized motion control for applications where space, speed, and flexibility are critical.
This model combines the power supply, drive electronics, and logic control into a single integrated unit, greatly simplifying the machine architecture and reducing both panel space and wiring complexity. The MC-4/11/03/400 is intended to be used in decentralized motion control systems, where each drive unit operates locally but synchronizes via high-speed digital networks, typically SERCOS.
It’s suitable for worldwide use, supporting a wide input voltage range (three-phase 380 V to 480 V) and designed to meet international standards for performance and safety.
