Description

Executing precise motion profiles across multiple independent axes, the QD70P8 serves as a high-density positioning module for the MELSEC-Q Series PLC platform. This module supports up to 8 axes of pulse-train control, enabling seamless integration with stepper motors and servo drives. Designed for centralized motion tasks, it offloads intensive positioning calculations from the main CPU, ensuring rapid system response times and highly synchronized multi-axis operations.

The module communicates directly via the Q-series base unit backplane, facilitating high-speed data transfer and simplifying system architecture. Typical operations include point-to-point positioning, speed-torque control transitions, and absolute or incremental motion profiles. By utilizing dedicated external I/O signals, the QD70P8 maintains robust control loop integrity and simplifies wiring requirements in high-density automation panels.

Features

Controls up to 8 independent axes using open-collector pulse train outputs.
Supports both absolute and incremental positioning methods.
High-speed startup capability to minimize cycle overhead.
Direct integration into the MELSEC-Q system backplane.
Diagnostic and monitoring functions visible via GX Works programming software.
Equipped with dedicated external I/O points for drive interfacing (limits, drive ready, and stop signals).

Applications

Packaging and labeling machinery.
Material handling and automated warehousing.
Multi-axis assembly systems.
Textile processing and winding equipment.
Semiconductor manufacturing and pick-and-place lines.
