The Mitsubishi Q172HCPU is a Motion Programmable Logic Controller (PLC) CPU unit from the MELSEC-Q QnU series, designed for advanced multi-axis motion control in industrial automation systems. It functions as a specialized motion controller that can be installed on the same base unit as a general-purpose PLC CPU, enabling complex, high-speed, and high-precision synchronized control of up to 8 axes via the SSCNET III high-speed serial communication network. It is engineered for applications requiring sophisticated motion profiles, such as interpolation and electronic cam functions.

• High-Speed Multi-Axis Control: Capable of controlling up to 8 axes simultaneously, supporting advanced interpolation functions including linear interpolation (up to 4 axes), circular interpolation (2 axes), and helical interpolation (3 axes).
• High-Speed Network Integration: Uses SSCNET III optical fiber network for connecting to servo amplifiers. This provides high-speed communication (speed command output up to 50 MPPS), noise immunity, and can extend over long distances (up to 800 meters).
• Diverse Control Modes: Supports various control methods including PTP (Point-to-Point) control, speed control, and position follow-up control, making it adaptable to a wide range of automated machinery.
• Multiple Programming Languages: Offers flexibility with support for different programming languages depending on the application, such as Motion SFC, dedicated commands, EIA language (G-code), and robot language (MELFA-BASIC IV).
• Compact and Robust Design: Features a compact form factor designed for backplane/rack mounting, with an operating temperature range of 0°C to +55°C, suitable for industrial environments.

As a core component of Mitsubishi's Q series PLC system, the Q172HCPU is built with industrial-grade materials to ensure durability and reliable operation in demanding factory conditions. It is designed for backplane/rack mounting and requires a 5V DC power supply from a dedicated Q-series power supply unit. The module includes a USB connector for easy connection to programming tools.

• Industrial Robotics: For controlling robotic arms with precise trajectory planning.
• Packaging Machinery: Enabling high-speed, synchronized movements in filling, capping, and labeling machines.
• Machine Tools: Providing accurate multi-axis control for CNC machining, cutting, and drilling operations.
• Semiconductor Manufacturing Equipment: Ensuring ultra-precise positioning and handling in production and inspection processes.

(*1) Q172EX-S2 cannot be used in SV13 and SV43.
(*2) This is the case of using an incremental synchronous encoder (SV22 used). When using a manual pulse generator, only one module is allowed.
(*4) Up to 8 of manual pulse generators and synchronous encoders can be used in total.
