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
