Mitsubishi Electric LJ72MS15-CM MELSEC-L Series SSCNET III/H Host Module

Description

Directing motion control data over high-speed optical networks, the LJ72MS15-CM serves as a dedicated SSCNET III/H host interface module within the Mitsubishi Electric MELSEC-L controller family. This module facilitates high-speed synchronous communication with compatible servo amplifiers, establishing deterministic control and complete noise immunity through optical fiber cabling. It integrates remote motion axes directly into the controller network, enabling precise multi-axis synchronization and real-time diagnostic reporting without electrical interference.

Features

• High-speed SSCNET III/H communication operating at a network transmission rate of 150 Mbps.
• Optical fiber communication link provides complete immunity to electromagnetic interference (EMI) and electrical noise.
• Seamless integration into modular MELSEC-L series PLC racks.
• Real-time diagnostic data acquisition from connected servo amplifiers.
• Highly reliable synchronous control suitable for complex motion profiling.

Applications

• Multi-axis packaging and wrapping machinery
• High-speed pick-and-place assembly stations
• Semiconductor and electronics manufacturing equipment
• Automated material handling and sorting systems

Installation Guidelines

• Mount the module securely onto the standard MELSEC-L system rack or DIN rail configuration.
• Adhere strictly to the minimum bending radius limits of the optical fiber cables to prevent signal attenuation or physical damage to the core.
• Ensure the optical ports are kept covered with protective caps when no cable is connected to prevent dust and airborne contamination.
• Perform all wiring and module insertion tasks with the system power supply switched off.

Compliance and Certifications

• CE Compliant
• UL / cUL Listed
