Mitsubishi Electric QD77MS16 MELSEC-Q Series Simple Motion Module

Description

Designed for high-performance positioning and multi-axis synchronization within the MELSEC-Q platform, the QD77MS16 Simple Motion Module delivers advanced motion control capabilities over the high-speed optical SSCNET III/H network. This module streamlines complex motion applications by integrating positioning control, synchronous control, and electronic cam functionality into a single slot design. By leveraging fiber-optic communication, the QD77MS16 ensures noise-immune, high-speed data transmission between the controller and servo amplifiers, making it highly reliable for demanding industrial automation setups.

The module supports synchronous operations such as electronic gears, clutches, and cams without requiring complex programming, relying instead on parameter-based configurations in GX Works2. It manages 2-, 3-, or 4-axis linear interpolation and 2-axis circular interpolation, enabling smooth trajectory execution for complex mechanical systems. It functions as an ideal interface for high-precision machinery requiring multi-axis coordination and centralized diagnostic monitoring.

Features

• Controls up to 16 physical axes via high-speed SSCNET III/H optical fiber network.
• Supports multi-axis interpolation including 2-, 3-, or 4-axis linear and 2-axis circular interpolation.
• Flexible coordinate systems and control units including millimeters, inches, degrees, and pulses.
• Stores up to 600 positioning data entries per axis for standalone trajectory storage.
• Provides advanced synchronous control features including electronic cam, electronic clutch, and electronic gear.
• Noise-immune fiber optic communication ensures reliable operation in high electromagnetic interference (EMI) environments.

Applications

• Packaging machinery and bottling lines requiring continuous-path synchronization.
• Material handling systems, gantries, and automated storage/retrieval systems (ASRS).
• High-speed pick-and-place systems and assembly lines.
• Semiconductor fabrication and wafer handling systems.
• Metalforming, cutting, and textile winding applications.

Installation Guidelines

• Mounting: Ensure the system power is completely isolated before inserting or removing the module from the MELSEC-Q base unit. Securely tighten the module installation screws.
• SSCNET III/H Fiber Optic Cabling: Always respect the minimum bending radius of the optical fiber cables (typically 25 mm to 30 mm depending on cable type) to avoid attenuation or physical damage.
• Grounding: Ensure the Q-series rack base unit is connected to a dedicated functional ground (Class D grounding, 100 ohms or less) using a heavy gauge wire.
• Shielding: Shield all external input/output cables and ground the shields near the module entry point to minimize noise coupling.

Compliance and Certifications

• CE (EMC Directive)
• UL / cUL Listed
• KC (Korea Certification)
