Specification

SEODescription

The Q172HCPU, a Mitsubishi Motion CPU module, serves as a high-performance multi-axis motion controller CPU designed for precision industrial automation. It supports up to 32 axes of synchronized motion control and directly interfaces with up to 16 servo amplifier modules via SSCNET III fiber-optic communication. The module includes built-in USB and RS-232 ports for programming and diagnostics, alongside compatibility with MELSECNET/H and CC-Link IE Field Network for seamless integration into factory automation systems. Operating within a 24 VDC ±10% voltage range and a temperature tolerance of 0–55°C, it is ideal for robotics, semiconductor manufacturing, and CNC machinery. Key advantages include real-time multi-axis coordination and robust network scalability, though its complexity demands specialized programming expertise.
