Specification

SEODescription

The **QD75M1 Positioning Module**, part of Mitsubishi's MELSEC QD75M1 Control series, is a compact motion controller designed for precise axis control in automation systems. It supports **1 axis of positioning** via differential or open-collector outputs, offering pulse frequencies up to 200 kHz for high-speed operations. The module integrates seamlessly with Mitsubishi PLCs via the Q-series base unit, requiring **DC 5–24V** power and operating within **0–55°C**. It features built-in **16 digital inputs** for limit switches and external signals, while relying on the PLC for additional I/O expansion. Ideal for CNC machines, robotics, and packaging lines, its key strengths include **easy parameter configuration** and **real-time monitoring** via GX Works2 software. However, its single-axis design limits scalability, requiring multiple modules for multi-axis setups. The QD75M1 excels in cost-sensitive applications demanding reliability and simplicity.
