Product Overview
The ELAU MC‑4/11/03/400 belongs to the PacDrive MC‑4 servo drive platform, originally developed by ELAU and later acquired by Schneider Electric. This unit is a compact high‑dynamic servo drive built for complex multi‑axis automation machinery. It executes closed‑loop position, velocity and torque control for servo motors, supporting high‑speed deterministic motion tasks. Widely used as replacement spare part for legacy production lines, it features integrated safety functions, flexible encoder feedback and expandable fieldbus communication options for retrofitting existing automation systems.
Series
PacDrive MC‑4 series is a modular servo drive system designed for packaging, material handling and processing machinery. The MC‑4 platform offers different current rating variants to match diverse motor power demands, supporting centralized and distributed motion control architectures. System expansion can be achieved by adding additional drive modules within the PacDrive rack setup.

Function
MC‑4/11/03/400 receives motion commands from upper‑level automation controller via fieldbus. It processes position setpoints, compares with real‑time motor encoder feedback, and outputs regulated power to drive servo motor. It performs full closed‑loop motion control including positioning, speed regulation and torque limitation. Integrated safety circuits cut motor torque when safety trigger signal is activated. Built‑in I/O handles local sensor and actuator signals, and drive diagnostic data can be read remotely for equipment maintenance.
Purpose
Deployed to drive and precisely regulate servo motors on automated production equipment. It delivers fast dynamic response, accurate positioning and reliable safety interlock for machinery. Mainly used as original spare or retrofit replacement for existing PacDrive‑based production lines.
Application Fields
Packaging machinery, filling machines, labeling equipment, food processing automation, printing machinery, material handling systems, converting machinery, factory automation production lines, legacy ELAU PacDrive system maintenance & upgrade projects.
