The Mitsubishi QD75M4 positioning module enables precise multi-axis motion control in automation systems. Designed for CNC, robotics, and industrial machinery, the QD75M4 module offers high-speed positioning, flexible configuration, and reliable servo integration.

Product Description

The Mitsubishi QD75M4 positioning module is a 4-axis motion control module designed for high-speed, precise positioning in automation systems. Part of the MELSEC-Q series, it interfaces directly with Mitsubishi PLCs, supporting servo or stepper motor control via pulse train outputs (200 kHz max frequency). The QD75M4 module operates on 24 VDC (±10%) and functions within 0–55°C, suitable for industrial environments like packaging, CNC machining, and assembly lines. It features embedded I/O for motion control signals, including axis start/stop inputs and status monitoring outputs. Communication is enabled via the Q PLC's base unit slot, with no standalone ports. Key advantages include multi-axis synchronization, flexible positioning modes (absolute/relative), and smooth acceleration/deceleration curves. Limitations include dependency on Q-series PLCs and fixed 4-axis capacity. Battery backup (optional) preserves parameters, while precise positioning resolution (up to 1 pulse/μm) ensures accuracy for micron-level applications. Compact DIN-rail mounting simplifies integration into control panels.
