Mitsubishi Electric QD75P2 MELSEC-Q Series Positioning Module

Description

The Mitsubishi Electric QD75P2 is a high-performance, 2-axis positioning module engineered specifically for the MELSEC-Q PLC series platform. Designed for high-precision industrial motion control, the module offers dedicated dual-axis control capabilities, supporting 2-axis linear interpolation and 2-axis circular interpolation. Utilizing open-collector pulse outputs, the QD75P2 integrates seamlessly with compatible stepper drives and servo amplifiers to handle complex multi-axis motion profile sequences.

Operating as an intelligent function module on the Q-Series backplane, it manages positioning tasks independently of the main CPU cycle, minimizing overhead and optimizing program execution speeds. It is an optimal hardware solution for systems requiring highly reliable point-to-point (PTP) motion, path tracing, and fast, multi-unit synchronization.

Features

• Supports independent or coordinated 2-axis control with linear and circular interpolation profiles.
• Provides flexible positioning units configurable in millimeters, inches, degrees, or raw pulse counts.
• Features battery-less parameter, positioning, and block start data backup utilizing non-volatile Flash ROM.
• Saves up to 600 positioning data points per axis, setting coordinates through peripheral software or PLC sequence programs.
• Advanced S-pattern and automatic trapezoidal acceleration and deceleration profiles prevent mechanical shock during operation.
• Enables seamless dynamic control through speed-to-position and position-to-speed switching modes.

Applications

• Packaging, wrapping, and labeling machinery
• Material handling gantries and pick-and-place systems
• Precision X-Y axis positioning tables
• Automated assembly and test fixtures
• Textile, paper, and film processing machinery

Connections and Interfaces

Installation Guidelines

• System Power: Ensure the main PLC base unit is completely powered off prior to inserting or removing the positioning module to avoid potential bus damage.
• Noise Abatement: Route pulse output cables separately from high-voltage AC electrical lines or motor power cables to reduce the risk of electromagnetic interference (EMI).
• Cable Length: Limit the external cable distance between the QD75P2 module and the servo drive to a maximum of 2 meters to maintain pulse signal integrity.
• Connector Assembly: Select the correct connector type (A6CON1, A6CON2, or A6CON4) and verify that all pin connections match the drive manufacturer wiring schematic.

Compliance and Certifications

• CE Mark (EMC Directive)
• UL Listed / cUL Listed
• KC (Korea Certification)
