Product Description

Description

System integrators requiring highly synchronized multi-axis control can deploy the LD77MS4 simple motion module to achieve high-speed positioning over a fiber-optic network. Designed for integration with the MELSEC-L Series PLC platform, this module acts as a dedicated controller capable of managing up to 4 axes of motion. It supports complex operations including positioning control, synchronous control, electronic cam profiles, and speed-torque control.

By utilizing the proprietary SSCNET III/H communication protocol, the LD77MS4 ensures high-speed, noise-immune data transmission between the controller and compatible servo amplifiers. This offloads calculation-heavy motion paths from the main CPU, ensuring deterministic, low-jitter performance across industrial manufacturing lines.

Features

  • Controls up to 4 independent or synchronized physical axes.
  • Communicates via high-speed, noise-immune SSCNET III/H optical fiber network.
  • Executes advanced motion control profiles, including electronic cam, gearing, and phase compensation.
  • Provides 4 integrated digital input channels for high-speed mark registration and limits.
  • Simplified system setup and diagnostic testing via GX Works2 engineering software.

Applications

  • Packaging machinery (form-fill-seal, labeling, and cartoning).
  • Material handling systems, including high-speed gantry systems and conveyors.
  • Automated assembly lines and pick-and-place systems.
  • Rotary cutters, flying shears, and winding systems.

Installation Guidelines

  • Always isolate all external power sources before installing, removing, or wiring the module to prevent electrical shock.
  • Use only specified Mitsubishi SSCNET III/H optical cables. Respect the minimum bending radius of the fiber-optic cables to avoid signal attenuation or physical damage.
  • Route the fiber-optic communication and low-voltage signal cables separately from high-voltage AC motor lines to eliminate electromagnetic interference.
  • Securely mount the module onto the L-Series DIN rail, ensuring the bus connectors are fully engaged and locked.
