Designed for high-speed, high-accuracy motion control, the QD75MH2 is a 2-axis positioning module engineered for seamless integration with the Mitsubishi Electric MELSEC-Q Series PLC platform. This module facilitates precise motion profiles by managing up to 2 independent axes of motion. By utilizing high-speed serial communication via the SSCNET III interface, the module establishes a direct, noise-immune fiber-optic connection with compatible servo amplifiers, minimizing wiring complexity and improving signal integrity over long distances.
The QD75MH2 positioning module is optimized for complex motion paths, supporting up to 600 positioning data points per axis. With an operation cycle of 1.77 ms, it delivers rapid response times and high-precision synchronization required for modern automated machinery. External interface signals, including limit switches and manual pulse generator inputs, are processed directly on-module to ensure immediate execution of safety and positioning commands.
