Product Description

Description

Designed for high-precision motion control, the QD75MH4 positioning module provides multi-axis synchronization and rapid response capability within the MELSEC-Q platform. This motion control module supports up to 4 axes of control, operating on a high-speed serial communication interface designed for seamless integration with Mitsubishi general-purpose AC servo amplifiers, specifically the MR-J3-B series. By utilizing a dedicated high-speed bus structure, it achieves an operation cycle of 1.77ms, significantly reducing latency and improving synchronization compared to legacy positioning systems.

The QD75MH4 is engineered for complex motion profiles, handling up to 600 positioning data points per axis. It includes robust external input interfaces for limits, stops, and manual pulse generators, making it a reliable solution for automated manufacturing, packaging machinery, and material handling systems requiring strict positioning accuracy.

Features

  • Controls up to 4 independent or synchronized axes.
  • Supports up to 600 positioning data blocks per axis for flexible motion profile configuration.
  • Fast 1.77ms operation cycle for dynamic path control and high-speed response.
  • Direct connection to MR-J3-B AC servo amplifiers via a high-speed serial communication system.
  • Integrated forced stop input (24VDC, 1 point/module) for hardware-level safety control.
  • Dedicated interface for a manual pulse generator (A-phase/B-phase, 5VDC, 1 point/module).

Applications

  • Automated packaging and sealing machinery
  • Semiconductor fabrication and handling systems
  • Multi-axis assembly lines and robotic work cells
  • Material handling and high-speed sorting conveyors

Installation Guidelines

  • Mounting: Securely install the module onto a MELSEC-Q series base unit. Ensure the lock lever is fully engaged to prevent communication interruptions on the backplane bus.
  • SSCNET Cabling: Use only specified fiber optic cables for SSCNET connections. Maintain the minimum bending radius of the cables to prevent signal loss or physical damage to the fiber.
  • Noise Shielding: Route the external 24VDC input signals and manual pulse generator lines separately from high-voltage AC power lines to avoid electromagnetic interference.
  • Grounding: Ensure the Q-series rack base is grounded to a reliable earth connection.
