Mitsubishi Electric RD77MS16 MELSEC iQ-R Series Motion Controller

Description

Designed for highly precise synchronization and multi-axis coordination, the RD77MS16 motion module operates within the high-performance MELSEC iQ-R Series PLC platform. This module delivers advanced motion control capabilities, facilitating high-speed, noise-immune communication via the SSCNET III/H optical network. Supporting synchronous control, electronic cams, and multi-axis interpolation, it serves as a central controller for complex positioning tasks across industrial automated lines.

The module connects directly to the system backplane, enabling high-speed data exchange with the main CPU. By leveraging optical fiber connections, the RD77MS16 minimizes electromagnetic interference over long distance runs, ensuring signal integrity in demanding industrial environments.

Features

• Controls up to 16 axes of motion over the SSCNET III/H optical network.
• Stores up to 600 positioning data points per axis for flexible trajectory planning.
• Supports multiple control units including pulse, mm, inch, and degree.
• Features advanced interpolation methods, including 2-axis circular and 2/3/4-axis linear interpolation.
• Provides optical network synchronization, eliminating cable noise and performance degradation.

Applications

• High-speed packaging machinery and wrapping systems
• Multi-axis printing presses and paper converting machinery
• Semiconductor manufacturing and pick-and-place equipment
• Material handling, logistics sorting, and gantry robotic systems

Installation Guidelines

• Power off the MELSEC iQ-R base unit completely before inserting or removing the RD77MS16 module.
• Secure the module using the base unit mounting screw to prevent vibration-induced disconnections.
• Use only approved SSCNET III/H optical fiber cables. Ensure the cable bending radius conforms to specified optical fiber safety limits to avoid signal attenuation.
• Maintain adequate clearance around the module vents to ensure convection cooling within the control panel.

Compliance and Certifications

• CE (EMC Directive)
• UL / cUL Listed
• KC (Korean Communications Commission)
