LD77MS2 | Mitsubishi Electric | Module de mouvement simple

Description

Designed to deliver high-performance motion control within the MELSEC-L PLC architecture, the LD77MS2 serves as a dedicated multi-axis Simple Motion Module. This unit facilitates ultra-precise positioning, synchronized control, and electronic cam profiles by leveraging the high-speed capabilities of the SSCNET III/H fiber-optic network.

Equipped with a single-system SSCNET III/H connection, the module provides reliable control for up to two motion axes. It incorporates dual high-speed digital input points featuring photocoupler isolation, designed to handle registration marks and limit inputs with minimal response delay. The direct fiber-optic link ensures complete noise immunity and fast cyclic updates between the PLC and servo amplifiers, making it ideal for high-throughput machinery.

Features

• Integrates a single SSCNET III/H communication port for high-speed servo network connections.
• Supports advanced motion capabilities, including synchronized control, electronic cam control, and speed-torque profiles.
• Features two points of photocoupler-isolated digital inputs configurable for positive or negative common systems.
• Delivers ultra-fast input response times of 1 ms or less for precise registration detection.
• Compensates for machinery layout limitations through optimized fiber-optic communication.
• Integrates seamlessly into the compact, modular MELSEC-L system layout without requiring a dedicated backplane.

Applications

• High-speed packaging and cartoning systems
• Automated material handling and sorting lines
• Precision labeling, marking, and printing machinery
• Electronic component assembly and pick-and-place equipment

Installation Guidelines

• Power Disconnection: Ensure all primary power sources to the MELSEC-L station are isolated and shut down before attempting to mount or unmount the motion module.
• Fiber-Optic Handling: Maintain the manufacturer's specified minimum bend radius for SSCNET III/H cables to avoid signal degradation or physical breakage of the optical cores. Keep protective caps on unused optical ports.
• Wiring Layout: Separate control and input wiring (AWG24 recommended) from primary power cables and motor drive outputs to minimize electromagnetic interference.
