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.

FAQ

Which servo amplifiers are compatible with the QD75M4?

The QD75M4 connects directly to Mitsubishi general-purpose servo amplifiers, specifically the MR-J2S-B series, via the SSCNET high-speed serial interface.

How many axes can the QD75M4 positioning module control?

The module is designed to control up to 4 independent or coordinated axes.

What is the maximum positioning data capacity per axis?

It supports up to 600 positioning data points per axis, allowing for highly complex motion profiles.
