Description

Designed for high-precision motion control within the MELSEC-Q automation platform, the QD75M4 positioning module provides robust, multi-axis control for up to four axes. Communication with servo drives is achieved via a dedicated high-speed serial network (SSCNET), optimizing synchronization and throughput across complex machinery layouts. This module supports sophisticated motion trajectories with a capacity of 600 positioning data points per axis, enabling smooth velocity profiling, precise target positioning, and flexible system configurations in demanding industrial applications.

Features

• Four-axis control capability supporting independent and coordinated multi-axis motion.
• Direct SSCNET interface for reliable, high-speed serial communication with compatible servo amplifiers.
• Memory allocation for up to 600 positioning data blocks per axis to manage complex movement profiles.
• Integrated inputs for crucial external limit signals, including upper/lower limits, stop command, and near-point dog.
• Built-in interface for a manual pulse generator supporting standard A-phase/B-phase differential or voltage inputs.

Applications

• Automated assembly systems and packaging machinery.
• High-speed pick-and-place and robotic handling systems.
• Material handling, synchronized conveyors, and sorting equipment.
• Multi-axis Cartesian gantries and coordinate-based positioning systems.

Installation Guidelines

• Power down the entire MELSEC-Q base unit before mounting or removing the QD75M4 module to prevent electrical damage.
• Ensure the module fixing hook is securely engaged onto the base unit, and tighten the module mounting screw to the specified torque.
• Keep SSCNET communication cables separate from high-voltage AC power lines and motor cables to prevent electromagnetic interference.
• Operate within a dust-free, dry control cabinet with adequate ventilation to maintain operating temperatures within official limits.
