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
