Description

Designed for high-precision motion control within the MELSEC-Q automation platform, the QD70P4 operates as a dedicated four-axis positioning module. This unit delivers reliable, independent or coordinated control of up to four axes via open collector pulse train outputs, interfacing directly with stepping motor drivers and servo amplifiers. By offloading complex positioning calculations from the main CPU, the module ensures rapid startup response times and stabilizes system scan cycles. It supports both incremental and absolute positioning configurations, making it a critical component for machinery requiring repeatable, synchronized movements across multiple axes.

Features

  • Four-axis independent or simultaneous control capability.
  • Open collector pulse train output design for compatibility with standard motor drives.
  • Automatic trapezoidal acceleration and deceleration profiles to ensure smooth mechanical transitions.
  • High-speed start times to optimize throughput in rapid-cycle operations.
  • Direct integration with MELSEC-Q series backplanes and configuration software.

Applications

  • Packaging and labeling machinery.
  • Automated pick-and-place assembly systems.
  • Material handling and sorting conveyors.
  • XY axis gantry systems and Cartesian robots.

Installation Guidelines

  • Mounting: Ensure the PLC rack power is completely shut off before installing or removing the module from the MELSEC-Q base unit. Secure the module using the integrated module fixing screw.
  • Wiring: Use shielded twisted-pair cables for pulse output lines to prevent electromagnetic interference (EMI) and crosstalk. Keep signal lines separated from high-voltage AC power lines.
  • Grounding: Connect the shield of the pulse signal cable securely to the protective earth (PE) or functional ground terminal on the panel or base unit.

Compliance and Certifications

  • CE Mark (EMC Directive)
  • UL / cUL Listed
  • KC Registration (Korean Certification for electromagnetic compatibility)

What is the maximum pulse output frequency of the QD70P4?
The QD70P4 supports a maximum pulse output rate of 200 kpps (pulses per second) using open collector outputs.

Does the QD70P4 module require an external power supply?
Yes, an external power supply is required for the output interface circuit (typically 5V DC to 24V DC depending on your drive interface).

Can this module handle closed-loop feedback?
The QD70P4 is primarily a pulse-output command module. It sends pulse trains to external drivers (like servos or steppers) which typically manage their own closed-loop positioning feedback.

Which programming software is used to configure the QD70P4?
It is configured using GX Works2 or GX Developer, where you can define parameters, positioning data, and starting coordinates.
