Rockwell Automation 1768‑M04SE Integrated Motion Control Module

Status: In Stock

DescriptionThe 1768-M04SE​ is a 4-axis SERCOS interface motion module from Allen‑Bradley’s CompactLogix 1768 series. It integrates directly into the 1768 chassis backplane, transforming a standard CompactLogix L43 or L45 controller into a high-performance, multi-axis motion controller. By establishing a deterministic fiber-optic SERCOS network, it enables precise synchronized control of up to four servo drives—ideal for packaging, material handling, and automated assembly applications requiring tight coordination between axes.

Application ScenariosIn a high-speed rotary packaging machine, the 1768-M04SE​ serves as the motion backbone. The CompactLogix CPU handles the machine logic and sequencing, while the M04SE​ module manages the real-time servo control. It synchronizes the main conveyor axis with the cutting axis and two labeling axes via a SERCOS fiber ring. This setup ensures that registration marks are read and acted upon with millisecond precision, maintaining cut-to-print accuracy even at high line speeds, all within a single, unified controller platform.
