Q173DCPU | Mitsubishi Electric | Contrôleur de mouvement

Description

Managing high-speed multi-axis synchronization within the MELSEC Q Series platform, the Mitsubishi Electric Q173DCPU Motion Controller delivers precise servo control for demanding industrial automation architectures. This controller operates as a dedicated CPU module on the PLC backplane, handling complex motion profile calculations independently from the sequence PLC program to optimize system response. Engineered to support up to 32 control axes, it minimizes execution lag with an operation cycle starting at 0.44 ms, ensuring high-speed tracking and perfect synchronization across dynamic mechanical setups. This unit comes complete with an external battery holder and a pre-installed Q6BAT backup battery to protect volatile parameters and absolute encoder positions during power cycles.

Features

• Multi-Axis Coordination: Capable of managing up to 32 independent or synchronized axes per controller module.
• High-Speed Operation: Microsecond-level control processing with an operation cycle limit down to 0.44 ms.
• Backplane Integration: Integrates directly into standard MELSEC Q series multi-CPU backplanes alongside standard sequence CPUs.
• Absolute Encoder Retention: Included Q6BAT battery and mounting assembly preserve coordinate tables and motion programs.
• Optical Communication Ready: Interfaces with high-speed SSCNET III motion networks for noise-immune drive synchronization.

Applications

• Continuous rotary web printing presses and registration control systems.
• Multi-axis pick-and-place packaging, cartoning, and bottling lines.
• High-speed material handling gantries and automated sorting systems.
• Precision metal stamping feeders and synchronized flying-shear systems.

Technical Specifications

Alternative Models & Compatibility

The Q173DCPU is designed to replace older legacy motion controllers within standard Q-Series backplane designs. When transitioning configurations from equivalent units, verify your software package compatibility inside MT Developer2. Ensure the system backplane's power supply module (such as the Q61P) is rated to handle the 1.25 A internal current draw of this unit combined with any concurrent sequence CPUs.

Application Pitfalls & Engineering Notes

When deploying multiple CPU modules (e.g., combining a Q03UDCPU sequence processor with the Q173DCPU), the motion controller must be assigned its designated slot order as defined in the multi-CPU configuration settings. Failure to set matching CPU parameters in both GX Works2 and MT Developer2 will trigger a multi-CPU synchronization error on startup, preventing the system from entering RUN mode.

Commissioning & Wiring Tips

Always maintain absolute cleanliness when handling the optical SSCNET III ports on the face of the Q173DCPU. Dust or oil film on the fiber optic interfaces will attenuate the signal, leading to transmission faults or axis disconnects. Leave the protective port plugs in place until the optical fiber cabling is ready to be locked into position.
