- PLC Motion CPU MELSEC-Q Series (Q173D/Q172D) by Mitsubishi electric.
- Compatible with the Q Series PLC (Platform) in the Multiple CPU system.
- The appropriate CPU modules for PLC control and Motion control can be selected to meet the application requirements.
- Control up to 96 axes per system using multiple Motion CPUs. (Three Q173DCPU modules use).
- Approximately double the basic motion performance and 1/4 the Motion SFC processing time.
- Increased debugging efficiency by reducing program read/write time to 1/3 the previous execution time.
