Description

Designed for high-accuracy multi-axis positioning, the QD77MS2 serves as a reliable 2-axis simple motion module within the MELSEC-Q Series PLC platform. Operating on the high-speed optical network SSCNET III/H, this module provides seamless synchronization and noise-immune communication with compatible Mitsubishi servo drives, such as the MR-J4 series. It integrates sophisticated motion control functions—including linear interpolation, circular interpolation, and advanced synchronous control—into a compact, standard Q-Series form factor.

The module is engineered to offload complex path calculations and speed-position switching tasks from the main CPU, ensuring consistent cycle times and high system responsiveness. Setup, parameter configuration, and diagnostic monitoring are easily managed using GX Works2 software, streamlining the engineering workflow for OEM machine builders and system integrators alike.

Features

Supports up to 2 control axes via a dedicated SSCNET III/H optical network interface.
High-speed communication rate of 150 Mbps with complete noise immunity over fiber-optic cabling.
Provides advanced synchronous control, electronic cam profiles, and virtual main shaft configurations.
Supports multi-axis interpolation including 2-axis linear and 2-axis circular interpolation.
Integrated inputs for external command signals, near-point dog, and stroke limit switches.
Seamless slot-mounting on any standard MELSEC-Q series base unit.

Applications

X-Y positioning and gantry systems
Packaging and labeling machines
Material handling and sorting conveyors
Automated assembly and pick-and-place stations
Rotary index tables and indexing systems

Installation Guidelines

Ensure the PLC base unit is completely powered off before inserting or removing the QD77MS2 module to prevent electrical damage.
Maintain a minimum bend radius for the SSCNET III/H optical fiber cables as specified by the cable manufacturer to prevent signal loss.
Keep optical connector caps in place when cables are not connected to protect the optical transmitter and receiver from dust and contamination.
Verify that the external input wiring is routed separately from high-voltage AC power lines to avoid electromagnetic interference.
