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.
