The Mitsubishi QD75D4N is a high-performance, 4-axis positioning module designed for the MELSEC-Q series programmable logic controllers (PLCs). It provides precise and versatile motion control for a wide range of automation applications. The module utilizes a differential driver output for robust and noise-immune pulse train signals, ensuring reliable communication with servo drives. It supports various control methods, including Point-to-Point (PTP) positioning, trajectory control with linear and circular interpolation, speed control, and JOG operation. Ideal for complex multi-axis systems, the QD75D4N offers exceptional accuracy and speed for tasks requiring synchronized motion.
